Not sure about Netflix, but 4k Dolby Vision / HDR10 through Jellyfin is fine. I don't know if I have any HDR10+ files to check, I'll find out and let you know.

Oh, cool. I read on the LineageOS wiki that Dolby Vision doesn't work on the shield with LOS installed, so good to hear that it works. The LOS wiki also says that Nvidia's AI upscaling doesn't work, so not sure if that's also the case.

Oh! So it turns out that I do know that HDR10+ doesn't work.

I had trouble getting season 2 of Fallout to play and only just noticed that it was HDR10+. Downmixing the audio to stereo let it play fine, I assume that may have forced a transcode to a lower HDR spec. It didn't look as flattened as it would if it were converted to SDR.

Also, the Shield isn't listed anywhere as supported hardware for HDR10+, even before degoogling. That may change if it's just a licensing thing. So FAR, I've only had one thing not play for me as expected, so I don't currently feel like I'm missing out on anything.

Also haven't tried any AI upscaling. Decent bitrate 720 is watchable enough for me, and I try to limit my exposure to anything marketed as AI anyway.

If those couple of things are dealbreakers, you could maybe go down the debloating path instead of a different ROM? If I get another Shield for my other TV, I might try that first and compare my experiences between the two.
