I've purchased the S9+ and received it on Friday (09/10/2018) as I've pre-ordered. I've noticed that HDR videos that I have on either the Micro SD card or copied to internal storage DO NOT playback the videos in HDR via the native video player. I have the S8 too and it is able to do so.
Obviously 3rd party apps like Youtube may need to release an update before HDR works there so that's understandable, but for the S9+ not to have this out of the box for the native video player is disappointing.
These clips are short 30 seconds recording on the Xbox One X and are full 4K HDR (Tomb Raider, Horizon 3 or Destinty 2 clips), and they play as they should on the S8 with 'HDR' showing when playing. However, on the S9+ it shows 'HDR' in bold near the title when the video plays, without the actual HDR enabled.
I've contacted Samsung, they've taken my details, serial number and IMEI number. They said they'll get back to me this week.
Just a heads up to everyone. I have the UK version, Exynos.
[Edit: 27/03/2018 - I do have colour grading issues, I was watching a HDR video at 1440p by Digital Foundry on YouTube and I can definitely see a sort of grainy presentation of dark and black areas of the screen. Black Crush is definitely present. Plenty of stuff on reddit and android central]
[Edit: I have chased Samsung and they called me back today (14/03/2018). They have escalated to their Product Support team as their Chat Team was unable to help and their other frontline support. They mentioned that they don't know when that team will get back to me as it's the first time anyone has raised it. I guess many people can't tell the difference and think HDR is working or it's actually working for them out of the box.]
Today I went to my local electronics store to check out the S9 and S9+. The lighting was pretty dim so I was able to spot it. Both S9 and S9+ had exactly the same issue (crushed blacks). Then I compared with note8 and s8 and they didn't have the problem.
So basically the bottom line is that all the phones have this *****.
Of course they were display models which are a little different from retail but at least the screen should be the same? Because again neither note8 or s8 have it. 😃
Just had this message from Samsung's UK Support's twitter account:
"We appreciate your patience. Samsung is aware of this symptom which may appear on some S9+ phones, and we've scheduled to release a new Software update to resolve this as soon as possible. Please keep an eye out for any updates to your S9+, we recommend keeping Auto Update turned on, so it installs as soon as it's available. ^JL"
