I just got my Chromecast with GTV yesterday. I've noticed that when I play 4K HDR content, only some of it will actually play in HDR.
About my setup: For Dynamic Range, my format preference is set to HDR. Also, I have it set to only output HDR when playing HDR media ("match content"). I have the Chromecast plugged into my AV receiver, which is hooked up to my projector.
This is how I test whether or not something is playing in HDR: When watching HDR content...
...if it's working correctly: Going to the Dynamic Range setting on my projector and switching it from 'Auto' to 'HDR 1' will not change the way the image looks.
...if it's not working correctly: Switching the setting from 'Auto' to 'HDR 1' will noticeably change the image. It will look oversaturated. It only looks normal when set to SDR.
I have tried a few different 4K movies on HBO Max and they all output HDR just fine. Same with Disney Plus. On the other hand, Netflix will play some HDR content correctly (Don't Look Up, Mindhunter,) but some content will be in SDR (I'm Thinking of Ending Things, Peaky Blinders -- both of these have a "4K HDR" badge when you open them). Prime Video played The Boys in HDR, but not Arrival or Mother. I rented Fury Road in 4K last night and that didn't play in HDR, which was surprising because I rented it on Google Play.
My Wi-Fi speed is good enough to consistently stream 4K content. When I use my 4K Blu-ray player with that AV receiver, the HDR always works fine. I'm not sure what the issue is. Any help would be appreciated.
