Do you know what white point the displays are being calibrated to? Do you know the luminosity at those measurements? What is the normalized coverage of the color space at different luminosity levels. Also, I think that you pay too little attention to the manufacturing variations or even different display grades/qualities/etc. produced from the same manufacturers, which can be substantial. Look at nits rating for instance on the new iPhone X compared to the Note 8, both OLED displays made by Samsung. Huge difference. My original point was that you cannot make the statement that Pixel 2 XL has a color accurate display or even a very good display at this point in time. We have to wait and see. Likewise, the only point that I was making earlier was that LG OLED displays have generally been sub-par when compared to Samsung OLED displays, and the Pixel 2 XL is likely using an LG display. It is possible though that we end up having LG OLED displays on phones as good as LG OLED displays on TVs.
