Question, I have an ATV 4K box latest gen with HDR10+ capability, I have a few movies in my iTunes library that offer HDR10+ but when I try to play them from my library it only plays in HDR10, The Thing digital copy for example, if I play it from watch now or continue watching in the ATV+ header it displays in HDR10+, anyone know why that happens?
My understanding is that it depends on the TV. For example I have a LG TV and it supports Dolby Vision & HDR - It does not support HDR10+. Similarly I have heard Samsung only supports HDR10+ and it does not support Dolby Vision & HDR.
I think the Apple TV converts DV to HDR10+ on Samsung, but I could be wrong.
It doesn’t convert, the HDR10+ metadata has to be there in the first place. Some Dolby Vision labelled movies do and some don’t, those that don’t will just play in standard HDR.
