I don't have perfect pitch so I can speak by experience, but there is this video on youtube where the parent of a kid with perfect pitch detunes the keyboard without telling him, and then asks him to identify pitches.

The kid really doesn't care, he notices that the notes are detuned but is not a problem to him, at some point he says that the note he is hearing is a mix between two notes and he is ok with that

Sorry for not linking the actual video, but I can't remember which one is, is the channel of Rick Beato if you want to try to find it
