Hang on, Apple don't calibrate each display individualy. They profile a characteristic display, and then apply that characteristic profile to all of their displays. If you want a calibrated display you will need to buy some calibration hardware! Displays change over time too...so frequent calibration is needed. Edit: If you want to prove this to yourself grab the display profile off another mac and compare it. It will be the same.
