I definitely don't think so. The humour in the "they still do not realise" memes come from the singular images presented, and the fact--or perhaps the assumption--that the identity of the impostor is already obvious to the viewer, adding comedic value by turning the whole situation into that of a dog trying to blend in with some fresh pastries, and of the fresh pastries not realising that one of them is a dog--or of the dog thinking that it has disguised itself successfully, where in reality its disguise was obvious, depending on the context.
In Among Us and its related meme-ries, the humour instead lies in two different perspectives: the subjects realising that there is an impostor amongst them--a very well-disguised one--as well as their comedic attempts to suss out who it is; or the impostors trying to kill everyone, and their comedic attempts to appear innocent.
The discussions that take place in a game of Among Us served to inspire not only single-image memes, but rather comics with small narratives, so I believe the two of them were never similar to begin with.
At least, that's my perspective.
