If Netflix didn't purposefully cripple its regular service in order to create a separate premium 4k/HDR/Atmos service level I doubt there would be any of these problems.I upgraded my Netflix plan to the one that does 4K/Dolby Vision/Atmos. And I've since downgraded. The LG TV app has random sound drop-outs every few minutes for a few seconds, and the Xbox One app has weird artifacting in the Atmos output. Other apps (Disney+ on both platforms) work perfectly, so seems to be a Netflix thing from what I can find. I'd rather have a stable stream.
The HDR mode is pretty killer on games. Have played some Borderlands 3 and Forza Motorsport 7 with it on.
