Not really. Yellow paint isn't a thing for shits and giggles, it's there to make the game readable.
Before yellow paint, games needed to have good art direction (instead of "realism") or good environment design to either make it clear something is meant to be interacted with or to point the player in the right direction.
Simply removing yellow paint doesn't suddenly improve art direction or environment design, it just makes the game needlessly hard to read.
Wrong. If the devs can't communicate something without copious amounts of yellow paint, that's a failure of design, not player intelligence.
