The main Earth of Into the Spiderverse is known as Earth-1610, and Peter B Parker's Earth is called Earth-616 (even if they are clearly not the one of the comics). I'd prefer for them to just use the official designation of Earth-199999. I get that they're doing it for the fanservice, but the problem is that fans who get the reference (such as myself), will also know that it's incorrect. It bothered me a little in Into the Spider-Verse and it bothers me here as well. At least Mysterio's reality, Earth-823, is a new designation that's never been used, so that's fine.

And to be fair, this kind of situation is similar to an X-Men storyline in which a group from another universe tried to invade Earth-616. In the main story, the invasion was stopped, but several alternate realities in which they succeeded have also been shown in which the alternate realities are each still referred to as "Earth-616" in-story, even though each of them has received its own official designation.
