>>741981i think it's exaggerated as an independent phenomenon, a lot of "creepy" uncanny valley stuff can just register as comical or normal in the right context.
that said, surely you've come across some 3d model, doll, etc. where the gap from a real human was at least a little unsettling? i got this pic from literally just googling "uncanny valley" and i do think it's a little creepy.
i think clearly humans just have an instinct for detecting things that aren't quite right and we receive it as something "eerie". but it doesn't have to have anything to do with resemblance between model and reality, it can be the feeling of walking through a familiar place and noticing something is off, etc.
