That doesn't appear to show HDR, the picture appears to be too pale. On the G6 those balls are a lot deeper. See the red shades in my 1st picture.

When I watch HDR content on the S8+, the colors appear to be pale/washed out/pastel. In that jazz video the red balls should be deep,bright red. The lightest shade is a hot pink. On the S8+, the lightest shade is a pastel pink.
It's the same effect as viewing HDR content in a non HDR screen. Pale/washed iut/pastel colors. Missing lighting n shadows.
The main musician has a shirt with gold patterns on his shirt. If I watch on the S8+ it appears to be a flat yellow. On the G6 it shows as gold.

Try watching the same video on youtube. On the S8+ this shows what the correct colors should be. Reds appear deep and red again etc. Don't know the extent but sure HDR is broken on the S8/S8+

Search on youtube for this:

I have moved HDR related to posts into a separate sticky thread to avoid mess up with HEVC discussion.
You can discuss all HDR related to stuffs here.

I've tested different 4K HDR captures (videos) from my Xbox One X and MX Player Pro is definitely not playing them with HDR where as stock Samsung's stock player is. It's definitely washed out colours and the darker areas appear pale instead of how HDR should be. I've compared on my 4K HDR TV and Samsung stock player with MX player. My TV has a pop up to say HDR and a banner on the S8 stock player. I believe Samsung S8/S8+ use Samsung's own HDR so that is also why Netflix doesn't support the device, where as the note 8 is supported.

Have you tried Video Enhancer feature?
If it's a system level implementation, MX Player HW decoder should replicate the stock player. Both are simply using mediaplayer API from android.

Hi Thirumalai, yes i've tried video enhancer and all it does it make a few video apps (MX player, YouTube, crunchy roll etc) a tad bit brighter. Made no real difference to what MX player does.

I have been trying many 4K HDR files on my Xperia XZ Premium, with all of them, regardless of codec, performing perfectly fine in MX player. However, there is one file I have come across that gives me performance issues, an HDR sample video from Digital Foundry (https://www.digitalfoundry.net/2017-...rt-hdr-sampler). Despite other 4K HEVC HDR 60FPS files (such as Sony's higher bitrate Swordsmith demo http://4kmedia.org/sony-swordsmith-hdr-uhd-4k-demo/) playing back perfectly fine, this one plays back choppily in HW+, and barely plays back at all in HW (SW plays back in untonemapped HDR with heavy slowdown, but that is the case for all HDR files I have tried.) The HW+ performance is the best out of the video players I have tried, with the stock sony video app playing back about the same as HW, and VLC performing worse than that in all modes.

Hi,

It may depends on the video encoding parameters. SW decoder won't be much smooth on higher resolution videos as it's not hardware accelerated. If HW+ is choppy, then your system decoders takes much time to decode the video frames. It may happen when you attempt to play the videos which is encoded in a profile or profile level that is not supported by the system decoder. That's why the playback of the particular video lags with every video player.

just for an example, if your system decoder can decode 4K HEVC @ 60fps, playing a video with more fps can make it choppy as system decoder can only decode only 60 frames per second. It's same for the many other video parameters (Like bitrate, resolution, etc).
