Just to throw in 2 cents here, I have tested HDR10 on both S8+ SD835 version and the LG G6 SD821. Only the LG G6 shows the correct HDR colors. The S8+ shows colors to be much lighter and paler. If you doubt this then try looking for a UHD version of the Smu*fs 2 with HDR10. On the S8+ all colors appear much paler in both HW and HW+ decoders using MXPlayer.
On the LG G6 they appear in the correct bright colors using both HW and HW+ in MXPlayer.
Even using the Samsung video player on S8+ gives the same dull colors so it must be something wrong with the device codecs, perhaps not having HDR support.

Just tried to screen capture on both playing the jazz demo video posted a few pages back but just blank so took a picture of both screens at once. Excuse the poor picture but I think you can guess which is the S8+ and which is the LG G6?

Tried playing the jazz demo HDR10 on my ZTE Axon 7 as a control (no HDR display) and same results as S8+, pale, dull colors. For some reason S8+ is not rendering HDR10 correctly. Perhaps this is why Netflix doesn't support HDR on the S8+ yet?

Bug report on ver 1.9, if I enable decoder, HW+ audio codec for a codec that doesn't show 'hardware acceleration' when playing a video with that audio codec it will playback scrambled sound. Tested on S8+ and LG G6 using that Jazz demo HDR10 video with aac sound. Was wondering why it sounded so strange
