I switch between Dolby Dark or Dolby Bright depending on what I am watching. I have just switched between the two to decide what to settle on and the picture is no longer actually changing when I switch between the 2 modes. There is a change in if I put it in Vivid but no change whatsoever for the Dark & Bright.
i have tried a reset, uninstalling apps (happening across all TV apps) and nothing. SDR modes are changing fine just not Dolby.. any advice to get it changing again would be super appreciated .
