65" Plus series supports DoVi and HDR10+. Works via Netflix, Prime, etc apps, those are profile 5. Trying to stream via media library app that has 7.6 and 8.1 movies and the TV can't play with them. Not surprising.
If I connect a player to the TV via HDMI and play 7.6 or 8.1 Dolby vision , will the TV play and recognize the video as Dolby vision?
