When I switch "HDR Always On" to 'Off', it displays everything correctly EXCEPT in never displays videos that ARE in Dolby Vision but says HDR instead. When I leave "HDR Always On" to 'On', it comes up with the Dolby Vision logo when one is played. So while it fixes the original problem, I lose Dolby Vision unless I go into settings and switch it back.
Can you please provide more information about the issue you are experiencing? Does this happen all the time or is it intermittent? Do all channels that you are watching content on have Dolby Vision or just some? Can you provide a tracker ID when this issue occurs (when you see this issue occur, press the Home button 5 times, followed by the Back button 5 times). In addition, if possible can you provide a video of the issue occurring so we can better understand what you are seeing?
Apparently, it DOES switch correctly on AppleTV, so the problem only appears to be with trying to watch Youtube. Those are the only apps I've watched so far that have DolbyVision content. I can live without Youtube DolbyVision, or at least I know how to work around it.
Forcing DV "Always on" just tricks you into thinking non-DV encoded content is DV, and isnt what you want (especially considering colorspace/colorimetry/tone mapping issues)
So, there is no such thing as "YouTube DV", go ahead turn "HDR Always on" off.
New TV, upgraded from Express to Ultra, and could not understand why DolbyVision was ON for all shows. Thanks for the solution (can’t believe Roku not only set HDR fo ON by default, but also buried it in Advanced)
