It looks so opposite to me ,I'm fine with SDR.
What's the color depth of my model ? Couldnt find it in specs, need to set it up in fire tv 4k
Update :
Interstellar 4k HDR YouTube docking scene looks amazing. I think rip ain't good.
I think I have the same rip based on the size you have mentioned. Looked great! I love the fade to blacks and dark scenes which merge into the darkness with OLED. Anyway, if you'll Google HDR looking dark, you can find various threads for the same issue. See if any of those has relevant information that can help. You should definitely check the specs of the panel. See the color depth and also the brightness. My Iffalcon TV has HDR too, but of course, looks mostly like SDR in a couple of shows I checked because of low brightness and 8 bit panel too if I'm not mistaken.
