Asgard, which is one of the infinitesimally small dimensions in the universe, is outside of a group of infinite dimensions that exist in an infinite number of mathematical dimensions, which easily makes it extraordinary. If one infinitesimal plane is outversal, imagine the infinite number of outversal dimensions in the Marvel universe. A universe in Marvel is easily Extraversal.
I find it difficult to interpret these scans in the context of spatial dimensions. The text says "
He decided it was time to investigate an odd thing he'd noticed about the universe. Namely that it was many-layered, composed of seemingly endless dimensions, indeed, it is a multiverse." and then travels to various realms. This appears to very clearly indicate that the word "dimensions" refers to realms, not spatial dimensions. I am assuming "spatial" was your intended meaning of "mathematical" dimensions.
The following scan says "infinite dimensional gulfs" which I suppose could be spatial dimensions, but again this interpretation seems somewhat counter-intuitive. With regard to the earlier scans, it seems like these gulfs are referring to the infinite realms, not spatial dimensions.
The Dark Dimension is one of the Dimensions in the universe, and has an infinite number of dimensions within it. The dimensions within the Dark Dimension were enormous, each one endlessly boundless. This alone makes the Dark Dimension multiversal in size. The Dark Dimension is also beyond the concept of space and time, which makes it a level of Complex Multiverse in size.
I can't cosign this assessment either. It seems to be referring to realms that Dormammu has absorbed into the dark dimension, and "beyond the concept of space and time" seems like a really generous assessment. The text says "Exists in a void of time and the laws of physics. Any light there is cold; it can be seen but it doesn't radiate energy." This doesn't read like transcendence to me at all. The Dark Dimension has an unfamiliar nature (time doesn't pass) but if there's light there and people can go there without issue, that seems like all it is.
The dimensions in the scan are
definitely not spatial. "The dimensions of infinity are endless. You could never hope to find him" "There are dimensions without end in this universe, and none can know which one will claim Dr Strange." This is definitely realms, why would a specific single spatial dimension claim Dr Strange? Why would Dormammu be able to "hide" in other spatial dimensions?
Yup, the Marvel universe is definitely extraversal in size.
These atoms aren't universal in size. They're literally infinitely small.
And a planet in Marvel is outversal, because it's platonic.
This is extremely unsupported even by the scans given.
I really don't feel like the scans support anything qualitatively beyond an infinite multiverse.
