You asked for more evidence as for if other universes are non-compactified. There was a previous CRT that covered the removal of High 1-C for Honkai before, it was unconcluded but it was rejected by many tier 1 experts.

Since you talked about String Theory being taking in, therefore the dimensions must be compacified, then please read the above posts. It'll be really helpful. Brane cosmology applies in the current scenario.
There is also this:
Carl explicitly said that dimensions can be infinite.
The OP
@Super_Nova argued against the scan:
Well, three problems:
- The scans refer to the number of dimensions, not their size.
- This would contradict the earlier statements about SoQ.
- Considering that the verse isn't High 1-B right now, I can accurately assume that there's a very good reason why these scans are untrustworthy. (Which I can expect is to do with the usage of the verb "can be")
First off, in the original thread that upgraded Honkai to High 1-C,
@Qawsedf234 was the one who argued that the scan talking about infinite dimensions is talking about dimensions are infinite in length, not in quantity. We also have no evidence Carl that is talking about quantity instead of length. But if you look into the gallery, do you really see a reason to assume its talking about the quantity of dimensions instead of the length?
Secondly, the scan would not contradict the earlier statements about the Sea of Quanta, because it is only said a "For example, a single universe has 4 infinite dimensions and 7 curled dimensions". It neither mentioned the Sea of Quanta nor any other universes inside the Sea of Quanta. Do you think statements would contradict since this is the actual case?
Thirdly... well, no one here is arguing for High 1-B. So I'm just gonna ignore that ragebait.
