James,
Since HDR is a mess right now and there is no definite standard yet to calibrate it yet I was wondering is you can implement a feature like the HDR Optizer to get the full potential out of our hdr screens. The Apple TV has enoug muscle to do so. Movies won’t look dim anymore especially on OLED displays:
“The DP-UB820 is equipped with a 2nd-gen Panasonic HCX processor, and works with both Amazon Alexa and Google Assistant voice control. It also has an HDR Optimizer tech that performs tone-mapping in-player before sending the signal to the TV”.
