iMac 27" 5K Retina

Finally had the chance of measuring the primaries on an iMac 27" 5K Retina
(latest INTEL Corei9 processor, 1TB SSD, the works). The numbers don't lie,
Apple is on the side of "P3", voluntarily distancing themselves from Adobe,
as the following graph shows:

I must confess I was pleasantly surprised/impressed by the quality of these
panels. Apple must have quite a stringent quality assurance program wherever
these babies are manufactured because the measured primaries were almost
smack on the nose of P3 chromaticities. So much so that, for all intents and
purposes, using the built-in ColorSync calibrator does the job. Except the
gradation, which, in all honesty, the built-in calibrator can't do. This was
easy to demonstrate to the Photoshop students who attended my class last
night, by alternating between Apple's iMac 'built-in' profile and the one
created with DisplayCAL/i1Pro2 @ native Luminance/WhitePoint, in
SystemPreferences > Display > Color. Owners of these computers might want to
consider investing into a colorimeter of some kind instead of resting on
Apple's built-in calibrator?
