Hi! Please, let me chime in with some data that may be missing in these discussions.
The first missing piece is
context related. The Bleed is 4-D in the Final Crisis series. However, in that series, it is a meta thing, in context, that contains the artwork itself in a literal sense. So, applying the DCU in-narrative version of Bleed from other series, with the Final Crisis version of Bleed that contains the entire DCU, is something that should not proceed onward.
Bleed 4D in Grant's series contains the entire paperverse of the DCU, it contains every dimension and every anything in any comic series. It contains the DCU, in a literal sense. When the Multiversity says Bleed is rotating in 5D, thats not the Imps 5D dimension...thats entirely a different context.
Multiversity understands that Nix alone is beyond Imagination.
This is a play on words, dimensions.
The entire DCU and every character in it is 2D in the 2D plane time
We are 3D, in Cube time, context nonfictional IRL stuff
Bleed is 4D, contains everything with a story.
Hypertime in Grants FC series is entirely the physics based version of Hypertime and not the classic DCU version that came later.
So when you see Bleed 11D later, or 5D bleed in Multiversity, you need to understand Grants context here has shifted from the Final Crisis version that contained everything, including the 3D Cube time.
I know thats confusing as hell. But that is the context. Bleed contained 2D fiction space called Plane Time, thats the entire DCU. And it also contained 3D space IRL Earth 33, nonfictional context where he said no fictional thing can go. Bleed is 4D and contains everything in the DCU.
the 5D reference is not the 5th dimension where Imps live when Nix by himself is referenced as beyond that imagation scope entirely. The usage of the word Dimension is being incorrectly asserted by some discussionists here and around comic debating forums and comment areas in general.
(Grant's Blog Post)
Context is difficult to keep between author series and it is why I always say the cosmology wiki entry's should be split. Yes, that makes it much more convoluted for the readers, but it is also a trove of honesty and full unbiased information attempts to get across to anyone reading. Those who want all the data and contexts should have access to all of it.
The issue is that the other author series, and even Grant's newer Green Lantern series, did not retain any of this context.
More so, Bleed in some series is regarded as 11D.
(sorry, the name of this comic escapes me at the moment)
In the Scott Snyder cosmology Guidebook called THE DC BOOK, this is said.
Which is alluded to here in JLA 2018
So...as I've said even prior to the end of 2018's run, Perpetua's multiverse is contained inside of Bleedspace, separated by a Source Wall she was placed into, and beyond that is the void of Bleed. The Bleed is the entire greater omniverse. We thought it was the Overvoid, the comic even denotes its the Overvoid. However, in the comic, more is learned, and the Greater Omniverse is discovered to be just more bleedspace that The Flash has been to in the past already.
One of those other continuums and past Multiverses was the COIE one that the original Anti Monitor deleted. It was still there in Hypertime and Pariah had access to it. The plot there was he was going to merge it with the N52 Multiverse and squish it, essentially making the N51 multiverse meaningless now in the wake of an infinite past Multiverse being copy and pasted into the space that contained the N52 multiverse. The end result was going to destroy the local 52 and allow the old COIE Multiverse to replace it.
Pariah had access to all of this, and the power of belief runs supreme in the Multiverse. This is why the Great Darkness was so potent, despite it coming from Pariah's mind and not being legitmate in that regard. Pariah had the totality power of belief for an infinitely large multiverse backing his Darkness. We learn in Flash Big Bang that The Flash rediscovered the locations in the Greater Omniverse and that he'd already been there.
More so, here are some older references for Hypertime.

Why is Hypertime important though? Because it is the opposite side of the coin to the Greater Omniverse, according to Batman's Schematics.
You can see he is speculating on what is beyond the Greater Omniverse in the chalk board area.
Whats beyond it, is more Bleedspace. We must understand that in each cosmology reset, and revision of the origins of history, the visuals of the map changes. Context even changes too depending on what realm or place we are speaking of.
In this case, at least in the Dark Crisis cosmology and "Current" era. We have discovered that Bleed > everything in the Greater Omniverse. And that even back in the older Death Metal era, the guidebooks agreed that Bleed connects and contains every multiverse in the Omniverse. Batman then discovered yep, the Greater Omniverse isn't the limit and that it's second side is Hypertime.
But all events are contains in Bleedspace, including Hypertime. We know this, 100%, because as shown and mentioned, The Flash and Lex Luthor both confirm the Greater Omniverse was a fabrication of data and an imbalance in the normal multiverse orrery that Pariah was exploiting. There was no Greater Omniverse. The Overvoid wasn't beyond the Source Wall. It was just more bleedspace.

JL Dark Crisis
So ya. The comics make this pretty clear on what DC wants you to think and feel over Bleedspace and the Greater Omniverse. Grant's Final Crisis Bleed is meta and shouldn't even be considered for inclusion with any other series. A split needs to be made to denote the differences in context.
The newer eras, well, we thought the Overvoid was beyond the Source Wall and that the Greater Omniverse was the space in the Overvoid. We were told the Source is there, Perpetua is from there, and so on.
Turns out nope, that isn't at all what it was. That entire location beyond the Source Wall was a locked off section of Bleedspace that contained more multiverses. So Perpetua and her Source, Hands and Judges and raptor, were all entities in Bleedspace and not what they said was in the Overvoid. This is quite literally debunked by the Flash and Lex confirming the Greater Omniverse is just more Bleed. Also, again, that flash had been there in the past.
That should clarify everything. Context is the key there and its important that we let wiki readers know there is a massive meta context differential between author series using the Bleed.
