Additionally, it's the intervals that give music its emotional content. For example, a minor third sounds "sad" while a major third sounds "happy". Absolute pitches are meaningless in this regard.

Playing a single note confers no meaning. It's only when subsequent notes are played that a context emerges, and music gains its emotional qualities.

Wonder if folks with absolute pitch form emotional associations with different keys.

Collier gives his answer to that here: https://www.youtube.com/watch?v=hyXCWYqpId4&t=836s and it seems to be yes for him, without giving any details why(!)

I would say it makes sense - perfect pitch or not - every key has a different relationship to your own voice, which makes it feel different.
