Today I got my first 4K TV with HDR10 + Dolby Vision, so I will check a lot of these games out on my PS4 Pro and my Xbox One X. I'll probably also try some PC HDR games with the new TV, when the announced "G-Sync compatible" firmware gets released.
It's an LG OLED55C9PLA with OLED, HDMI 2.1 and very low input lag. The Xbox One X already can connect with it in the display modes "4K 60 Hz 10 bit VRR" (variable refresh rate, FreeSync) or "1440p 120 Hz 10 bit VRR"... but I'll have to wait for PS5 or Xbox Scarlett for the full "4K 120 Hz 10 bit" experience (with 30 fps locked games) 
I temporarily disconnected my PSVR, since I have the old model without HDR passthrough. :(
