I’m confused here.
MakeMKV has had the ability to create a Single Layer Profile 7 whilst retaining Dolby Vision for the last few months. It’s how many of us with an NVidia Shield has been watching them.
- MakeMKV v1.15.3 (1.10.2020 )
- MakeMKV now can extract Dolby Vision metadata from elementary stream data and rebuild missing or invalid DV descriptors
These are definitely not “Fake DV.”
I can assure you the latest Plex Testflight plays them just fine as DV (as long as the Atmos soundtrack is disabled.)
Further to this one high-end tracker has just released the very first 1080p Single Layer Dolby Vision encode. Here’s the Media Info for it. It (2017).txt (7.5 KB)
Here hopefully if the link works is a 1 minute (crap quality) video of Plex triggering Dolby vision on two Profile7 Dolby Vision files. Sadly the Dolby Vision logo itself is highly reflective.
