ATV dosent have an USB Port, so you need to stream your Files over Network.

With the MrMC App you see wrong colors if the DV MP4 uses ICtCp color format (known issue but no fix yet).

I believe with Infuse 6 ( https://firecore.com/infuse ) you can view DV with right colors (DV Support is a Highlight Feature) but i dont checked it because Infuse is not cheap and i dont like subscription plans.

Infuse supports Dolby Vision Profile 5 only. I need profile 7 support.

I think there is no Player App on ATV that supports dual layer DV at this moment.

The famous Plex Player also supports only single layer DV.
