With the new update 7.2.1, I tested a demo clip of Dolby Vision Profile 5 (not a show or a movie, just a test clip from Dolby). The issue lies where Infuse does not indicate anywhere that the test clip is Dolby Vision, only the resolution (4K).
It should detect if it’s HDR or DV and indicate it. Test clip was added after updating to the latest version. I can send the test clip if requested.
