so what we need is some kind of quantification, in the end it's all about the size (pun intended)
let's say if there's a realm is it infinite in size? if not how big is it, is it as big as a regular universe?
when there's a multiverse, is it a multiverse consisting of infinite universes?
and in the end as long as a multiverse has infinite universes, it is infinite by nature, we know 616 universe is by itself a small multiverse which other domains and dimensions, but there is a bigger multiverse encompassing that universe too.
marvel just like dc has mentioned they have infinite universes, which coulld be intepret as a multiverse/omniverse in comics, and really anything beyond that is just semantics when we comparing all third dimensional space/time
aside from that we can get into another topic where planes of existence above the traditional third dimensional universes, and that was only really discussed thoroughly in dc where every dimension is infinitely larger than the previous one.
higher plane of existence view the lower plane of existence as dust, a multiverse consist of infinite universe could be a germ compare to higher realm
