Do children with "perfect pitch" consider as Gifted?

I myself have "perfect pitch".  But I did not realize this is a special talent until around 13 years old.  But I got grade 8 piano at around 14/15 years old.  I was the accompanist/pianist for school choir and teacher always asked me to give A or C when there is no piano.  Having perfect pitch is excellent when you need to hear the interval (of two notes) during aural piano exam.  But having perfect pitch is awful when you are given a musical score and have to sing it at a lower scale (e.g. 2 notes lower, 唱低兩個key).  For example, I see a "C" on the musical score, but as everyone is singing 2 notes lower (transpose), then I would be very busy, having to move all notes 2 notes lower in order to match every one's pitch!
