Okay you got me thinking about this a bit, my own hardware is not DV capable so typically I just avoid media that is DV only. But for experimentation I tested a few media players on Windows

• Jellyfin
• Kodi
• MPC-BE
• MPC-HE
• MPV
• Potplayer
• VLC

Interestingly with default settings none of them will playback DV with tonemapping (no HDR, just DV only aka DV Profile 5).

I did figure out additional settings for one of the media players, MPV will do DV tonemapping if you add "--vo=gpu-next" to the command line on startup e.g.

mpv --vo=gpu-next yourmediafile.mkv

No idea on any of the other media players, there weren't any obvious settings to enable for DV tonemapping.

Reference re: mpv https://github.com/mpv-player/mpv/issues/9506

What software are you using? Most modern software can already do HDR tonemapping so it would look normal during playback.

I think the issue for you is that you are downloading files that are DV only, no HDR fallback, and AFAIK media with DV only cannot be played back with tonemapping (hence why you are seeing it all pink/puple/green). To properly play DV media you'd need DV compatible hardware - I don't have that type of hardware so someone else may be better able to explain those constraints. My desktop is a bit on the old side LOL.

But anyway in the future you should download media with the HDR tag or media without any DV/HDR tags.

PS - If you run your media through something like mediainfo and give us the output that should give a more accurate idea of your issue but I'm pretty sure you just happened to have downloaded a DV only file.

EDIT - On second thought some playback software seems to support DV tonemapping nowadays. It's been a while since I tried testing that myself, seems easier just to avoid DV only media. Maybe double-check that the playback software you are using supports DV tonemapping and figure out how to enable it.

I think the purple/green tinge is caused by Dolby Vision HDR, not Atmos. Atmos is some kind of surround-sound standard.

There's a different HDR standard that causes washed out colors (again, I think).

I don't know how to handle either one without actually getting equipment to handle them.

You want to download hybrid HDR releases, e.g. HDR10+DV

I think you mean Dolby Vision

It is possible to tonemap DV to SDR, and I think to static HDR as well. Look into madvr and/or mpv. Both should be able to provide real-time tonemapping during playback. For reference, these pink/green videos would be DV Profile 5 (P5). I've heard the results are not great, so I would stick with P8 hybrid releases.

The purple green thing is the privacy protection for Dolby Vision in action. I dont have a fix, apart from to keep downloading different releases until I find one that just works™️
