I meant color calibration. I don't work for Apple. I had a non-Apple iPhone 4 screen replacement and the colors were washed out, lacking saturation - it's impossible for me to say whether that is due to display quality or lack of calibration. However it makes sense to me that color calibration is required for consistent display performance especially when displays are sourced from different manufacturers.
