Have a Samsung Q60R. I noticed when the disney app is selected, the dolby digital+ is not selectable on the tv, unlike when i use Netflix or plex, these options are available. TV passes trough a Denon AVR , works 150% on Netflix, Plex, Playstation and xbox, all of which the avr auto configs individually. I can get 7.1, atmos and all the bells and whistles from Plex and Netflix and so on....but Disney plus is stuck on a forced 5.1 basic (which the avr says, TV SURROUND. Also, no HDR or 4k. it seems the highest the tizen app can go is 1080p. I have good net speeds and Netflix pushes 4k with ease. Hope they update this. Its not a train smash, the app runs smooth and movies still look good and sound good...but it CAN be better.
