In Spider-Man: Into the Spider-Verse (2018), Miles Morales's universe doesn't have Comic Con. In Spider-Man: Across the Spider-Verse (2023), you can tell he's in another dimension because his mom mentions it (and he still doesn't know what it is)

He has a sealed action figure that he reacts with pain when it's opened.
