Just got an X (64GB Silver) and noticed right away my screen looked a little off. Blue shift isn't that bad, but I compared it side by side with some display models (full brightness, true tone off) and whites on my screen have a pinkish/yellowish, dingy look versus a more clean, true white. As you lower the brightness, the dirtyness of the X also becomes more apparent. Not something I'm willing to accept on a $1000 phone. Unfortunately, all the Best Buy's in my area are out for 2+ weeks now, so its looks like I'm just going to have to return it and wait.
Edit: here are some comparison pictures between an X, Pixel, and 8 Plus. The Pixel is also a Samsung OLED panel but the whites are much cleaner. And I was actually surprised how close the Pixel whites were to the LCD of the 8 Plus.
There have been worse X screens posted in this thread, but as I mentioned above, I'm not settling when the device costs this much.
