Tossing in my use case as a data point; Both are 17 PMs at about 50% brightness, the silver (left) has a Samsung screen (G9N), the orange (right) has an LG (GH3) - couple observations:
-The Samsung panel holds onto the white color temp better, and does not introduce any tint or color shift at side-to-side or top-to-bottom angles. I watch a lot of videos and the LG's color shift is noticeable when moving the phone into and out of landscape.
-The LG panel has better uniformity when looking straight at the screen. The Samsung has a small amount of yellow-to-blue, or "warm" to "cool" color shift variance depending where I look on the panel. So reading website articles with a white background and black text is more pleasant to my eyes with the LG.
Additionally, after reading for an extended time, I find the LG panel to be "softer" to my eyes, in that I don't feel I suffer from PWM symptoms, but eye strain is a real thing and the Samsung panel seems to tire mine more than the LG.
Would I have noticed each panel's nuances if I didn't have them side by side? Probably not. Color shift on off-axis viewing with OLED has been around for a decade and a half and seems to be an accepted limitation of the technology for most consumers. Personally I wish mini-LEDs would advance faster than they have, but it sounds like that's still a ways off.
