Perfect pitch is not correlated with the ability to see written notes and immediately know how to play them on any instrument. It is only barely correlated with the same but for singing the note.

I do not have perfect pitch, but I could always do what GP's kid does. I am now a pretty good amateur singer.

What matters for this is learning to read the music notation and developing a sense (mostly subconscious) of scales and harmony. Perfect pitch does not help either of those things.
