Wondering if Apple is using the 9CA3 exclusively in the mid 2009 15" mbp. Have not seen any other screen model mentioned for the 15", whereas a variety of screen manufactures are used for the 13"mbp. Have seen the 15" mbp in an Apple store and the colors "pop" out more than on the previous version. Had one 15" sitting next to the 24" led display and the screens looked almost identical in quality and color - well at least to me. I am no expert on displays but giving my thoughts on what I compared and seen.
