Google responds to the Pixel 2 XL screen controversy

Even if you boost the screen colors of the Pixel 2 XL in "vivid" mode, the testers claim, they still remain lifeless in comparison to, say, Samsung flagships' default mode, or even to the retail V30 units. Moreover, no amount of software updates can fix irregularly lit pixels resulting in scattered brightness spots, which is likely a result of the active matrix passing more current than needed to light up some individual pixels, but we'll take a deeper look at the displays on the retail units, and let you know if there are any issues you can't live with (unlikely). 

LG's P-OLED screen tech stands simply for plastic OLED, one with an underlying polymer instead of rigid glass substrate, allowing for thinner, more flexible displays, which is what Samsung also uses for the curved screens of, say, the Note 8 and S8. That being said, though, the quality of those plastic OLED screens depends on many other input components like the plastic compound mixture used, the type of organic materials used for the LEDs (especially the blue pixels which degrade the quickest), and even the sub-pixel matrix arrangements. LG doesn't have the years of extensive experience Samsung has with flexible OLED displays in retail handsets, and it might be that their P-OLED technology needs further fine-tuning and improvements to reach its true potential.
