Xbox One S - Playing a HDR demo/movie does not put my TV into HDR mode

Plex Players Gaming Consoles

  • Gears of war 4 does this fine
  • Also Samsung Hub PLEX on my new Samsung KS8000 TV does this fine
    BUT Samsung HUB PLEX does not have enough cpu to handle 4K HDR so its not an option :¬(

Any idea if this is in the pipeline?
Last thing I need is another box attached to my system - heheh
