apple tv 4k dolby vision on all the time or not

[y2jman]

so we all know i recently got tcl q6 that now does dolby vision and atmos

i read its ok to leave dolby vision on won't hurt nothing q6 models i don't know leave it on that or have it 4k sdr since it switches back to dv and none dv

i got both range and frame work turn on

what do you guys think i should do still trying to figure out want dolby vision bright or dolby vision dark when i watch stuff on apple tv or when i watch 4k movie with dv on it

plus i don't know what picture mode to do apple tv 4k its on movie mode<-just like on bd dvd when i watch a movie on 700 4k bluray player

also i notice something how come when watch something disney plus it will show dv symbol but if you go to another app that has dv and go back to that same movie or show disney plus dv symbol goes away

somebody regedit i read mention that The Disney+ app has a known issue that match content stops working when you exit the app, use another app that supports it and go back. But force closing the app makes it work again (double press TV button to bring up the app switcher and swipe up to close the app). But of course only until you dare to leave the app again. So the best thing to do is to force close and open the app everytime you want to watch something on Disney+.

i been like restarting apple tv when this happens then going back to app and symbol come up again
