For those of you that are interested, here's a measurement report of my 12,9" iPad Pro display.

Some notes:
Used Splashtop remote desktop to run DisplayCAL on macOS High Sierra (which is also why the display device is reported as EV2750)
ISO 2008 test chart. This is more challenging than what you're likely to see in reviews, however it's still a quick test. Because of time constraints I settled for this but a bigger/better test chart would, most likely, have highlighted more errors.
The test instrument is a ColorMunki Display (same as i1 DisplayPro, but slower) which is a couple of years old. It has not been calibrated.
I have assumed the iPad Pro uses WLED backlight, which is most likely the case but I can't know for certain.
As for the results you may note that the contrast ratio here is lower than in some reviews (like Anandtech). That's because they measure at maximum brightness. I've measured at 105 nits, which is rather bright in a dimly lit room.
The color temperature is too cool at 6900K. The relevant measurement here is "measured vs display profile". The "display profile" here is the sRGB target.
The iPad Pro looks to be targeted at a 2,2 gamma instead of the sRGB gamma function. It's a slight difference, but it is there.
Color accuracy is very good. About as good as it gets for a display without proper calibration.
