If you have an LG OLED TV you can push 11111 over the Channels > Channel Tuner menu (I think? Google this if it doesn’t work) and it will show you a screen of input stats. If you use the arrow keys and OK buttons you can open an HDMI sub-menu which shows you the input signal as 8-bit or 10-bit. Via a Club3D DP1.4 to HDMI 2.1 adapter I was only able to get 8-bit HDR according to the LG TV. Your other monitors might tell you more details maybe? I’m away from my setup but I could post a photo later and more details on the connections and cables. I tried 3 different USB C DisplayPort adapters with the same results on each... I plan to test what the LG TV says for an Nvidia 2060 soon too, to compare...
