Pixel 2 XL owners took to social media to voice their complaints about discoloration and screen burn-in. The first issue Pixel 2 XL owners started noticing was the screen's inconsistent colour temperature, most noticeable when viewing anything with a white background.
The screen has a warm colour temperature but if you look at slightly off angle the colour temperature changes to a bluish tint.
While there are some real advantages to OLED displays over traditional LCDs - they're thinner, more power efficient, brighter, and display more vibrant colours and deeper blacks - they're also prone to defects like screen burn-in.
Samsung has not figured out how to sort out the problem. The Super AMOLED displays used in its Galaxy S8 and Note 8 phones are rated as the brightest screens for mobile devices by DisplayMate's but they're susceptible to burn-in. To prevent burn-in from the screen's virtual home button, Samsung's programmed it to move by a few pixels every few seconds.
While the Tame Apple Press is happy that the Pixel might turn into a mess for Google, it might have a few problems of its own with OLED screens on the iPhone X so it should be careful what it says.
