but the pitches on the piano are not perfect, aren't they ? It uses equal temperament iso just temperament. So shouldn't a piano sound out of key to you ?

  That's not what perfect pitch means, per se. It should work with any tonal system.

    Suppose you're calibrated to an G1 on 49Hz. You get exposed to a wave at 61.25Hz. Do you consider it to be a B ? For me, the major third on a piano sounds different ('off') from where I imagine it to be.

      I don't know if it works by calibrating a note to a frequency, so much as being able to hear the intervals perfectly.... but I don't know for sure, my own pitch is only of modest quality
