MBP Retina Display Delta E & Uniformity
The following data is from my fully loaded BTO Macbook Pro w/ Retina display built in Sept (ww36). Apple is using two different suppliers for the screens in the rMBP - Samsung and LG. The Samsung is a S-PLS display while the LG is an IPS display.
The Samsung and LG displays have very different characteristics. This leads to a lot of debate on the Internet when people talk about the display quality of their rMBP. You can't directly compare two different screens. Before there can be any discussion you would first have to identify which display your rMBP is using ( http://macperformanceguide.com/blog/2012/20120804_1-MacBookPro-Retina-screen-burn-in-followup.html )
BTW, the LG displays have been known to have an image persistence issue so it may have an effect on your photography work. ( https://discussions.apple.com/thread/4034848?start=0&tstart=0 )
My rMBP has a Samsung S-PLS display. I have calibrated it with an i1Display Pro and i1 Profiler software with the following settings:
Luminance: 100 cd/m^2
The native WhitePoint for this Samsung display seems to be close to 6500K. The white uniformity is within 10%. The average Delta E is 1.04.
