Will a movie with DV profile 7 and HDR10+ fallback to HDR10 on ATV 4K?

Video Playback

When I played a movie on an LG B5 I thought that since it can’t play DVP7 and the tv does not support HDR10+ that it would fallback to HDR10. But in the infuse playback stats all my movies in this scenario show up as playing in HDR10+. This also happens when a movie only has HDR10+ and no DV metadata. I tried other tv’s, screens and monitors that only support HDR10 and the results are all the same - showing HDR10+ playback in the infuse playback stats.

The video playback quality seems to me like it’s…fine? To be honest, it’s hard to really tell if the playback in these scenarios is accurate to HDR10 or if it’s doing some kind of conversion.

Is this a glitch with the playback stats showing HDR10+ but it’s actually playing back in HDR10?
Or is infuse actually trying to playback HDR10+ metadata on a device that doesn’t support it?

Below is the HDR format media info for a couple movies that act this way:

  1. Saving Private Ryan: Dolby Vision, Version 1.0, Profile 7.6, dvhe.07.06, BL+EL+RPU, no metadata compression, Blu-ray compatible / SMPTE ST 2094 App 4, Version HDR10+ Profile B, HDR10+ Profile B compatible

  2. The Martian: SMPTE ST 2094 App 4, Version 1, HDR10+ Profile B compatible

Just to be clear, movies with HDR10 metadata do show up correctly as ‘HDR’ in the playback stats. The issue is just with movies holding HDR10+ metadata.

HDR10+ is backwards compatible with HDR10 so when HDR10+ content is played on a TV that only supports HDR10, the dynamic metadata features are ignored and the content plays in regular HDR10.

Dolby Vision Profile 7 is not supported on any Apple TV model, so in this case playing the HDR10+ portion of these videos would be appropriate.

Hi James!

This is correct so for clarity (and my sanity), when Infuse ‘playback stats’ shows it’s playing back HDR10+ on a device not supportive of HDR10+ it’s actually falling back to HDR10, right?

I’m sorry for my ignorance, my confusion comes from seeing HDR10+ on the ‘playback stats’ when I would have thought it would just state ‘HDR’ like other files that just have HDR10 metadata. I really appreciate your response.

Correct. What you see on your TV would be native HDR10 content. Nothing is being lost or tonemapped when playing HDR10+ videos on a TV that only supports HDR10.
