Take that video and even his previous video with some salt though, I don't think he has set up the LGs brightness or Contrast correctly to match the Sonys OLED or maybe needs LG tvs calibrated.

The sony appears washed out, blacks should not be grey or white, whole point of OLEDs is inky blacks not white washed out blacks obviously. The LG gets it accurate with the deep blacks but even then looks like it is off with some setting here.
Wait for Vincent Teoh to show us the properly set up A90j vs C1/CX hopefully soon.
