My C9 OLED shows the same information - 8 bit color pushed when using 120hz.2016 Sony XD70 4K HDR. Old already. Seen XH90 in person and that shit looks as close as it gets to OLED which is mind-blowing for only 32 local dimming zones. Only shows that Sony are masters of processing and algorithms.
Getting XH90 after 1-3 months when my financials are settled as buying Sony a7S III which is fucking expensive.
These HDMI short comings and the overall shoddy implementation of video settings compared to Xbox are frustrating (automatic everything) HDMI 2.1 implementation is what I was most looking forward to with next gen and thus far Sony has dropped the ball.
