I was reading about extended Dolby vision on some older posts. And I found that it doesn’t exist anymore on Infuse, and more surprisingly can’t find any mention of it disappearing on this forum. So why did it go?
@GaryHowe
It’s basically baked into the app now since Apple started to support profile 8 natively. (Previously Infuse were doing an on the fly conversion for profile 8.) This pretty much made the setting redundant.
By default if Infuse can play the file as Dolby vision (so most Profiles 5 & 8) it will.
For profile 7 it will use the HDR fallback.

Okay thanks. But I’ve got a Dolby vision profile 8.1 file that won’t play as Dolby vision. The Dolby Vision logo appears on screen, but it absolutely is not Dolby vision, it’s HDR. Any ideas?
Could you run that video through mediainfo and post the results here?
Sure, here it is.

Is that what you wanted?
Which model Apple TV do you have?
Can you describe the issue you are seeing with the picture when playing this video?
It’s the latest Apple TV 4K only a few months old. The issue is what I’ve already said, it’s not playing as Dolby Vision. The Dolby Vision logo comes up but it isn’t Dolby Vision it’s HDR. It has none of the vibrancy and brightness of Dolby vision and if I change the Apple TV to HDR the picture looks exactly the same as when it’s supposedly playing in Dolby vision
There are some video encodes in which Dolby Vision basically does nothing. How do you know on this specific video it is supposed to look “better” than HDR?
if the brightest content in this video is actually 246 nits, then it’s basically SDR.
Okay thanks. So the problem is that it’s just a crap quality file by the sound of it.
