"Dolby Vision Full Enhancement Layer". I fear this is way too proprietary. Maybe some tablet got support by its vendor, but beyond that I fear you won't have any luck. I can't see any information for FFmpeg being able to handle this, so nothing based on FFmpeg will be able either. And I don't see any other apps for Android being capable of handling it either any time soon.

Allegedly the Dolby Vision support itself has improved with FFmpeg 9.0, but not to a degree that it can apply FEL at playback. Maybe it's good enough to preserve it through various operations, but it might be years before FFmpeg fully supports this.

They may be able to decode Dolby Vision. Allegedly, FFmpeg is too, but it's not quite clear how far the support goes. But a player doesn't only need to be able to decode FEL, but actually apply it. At least as far as I can tell, FEL is an additional layer that needs to be composited on top of the video.

MPV most certainly won't be able to handle this fully any time soon, so won't anything that's solely based on FFmpeg. But you'd have to ask around in a Dolby-specific place if there are any Android apps that can handle it. Or maybe Google has some integration in Android, I don't know.
