As far as I know Lenovo is one the few manufactures that make Oled tabs with Dolby Vision support (The Samsung Oled tabs does not have that)
However, I have never got Dolby Vision to work in Kodi on the Lenovo.
The files i am trying works perfectly with Dolby Vision in Kodi on my Philips OLED TV and Shield.
I have searched and found others with similar problems on the Lenovo P12 Pro
I have the Lenovo P11 Pro myself right now, but am interested in getting the Lenovo Tab Extreme (Legion Y900) 14" Oled with Dolby Vision if I can get it to work with Kodi
Any hints or suggestions ?

There's a Video section in the system info that tells you what HDR formats the OS supports. You could start by checking there.
Otherwise post a debug log.

That's more of a problem. Won't work in HDR that way. I would start with a standard DV file
First decide what functions / features you expect from a system. Then decide for the hardware. Don't waste your money on crap.

Your firmware does not seem to support a hw decoder for this kind of codec and falls back to SW.

I also have the Lenovo P11 Pro and have been unable to get any DV file to play in Kodi.
Tried many different builds including quietvoids work before it was merged in to master.
Every time no matter what profile version of DV I tried I would just get a black screen in Kodi with a bit of audio and then nothing.
I know this isn't particularly helpful to fix the "issue" in Kodi but I tested many different applications to play these files and ended up using Emby with JustPlayer (Legacy) as an external player.
Emby plays the DV files perfectly but when a file has dolby audio it tries to use ffmpeg software decoding and stutters like crazy, DTS audio files play fine with DV enabled.
Using Justplayer (Legacy) as an external player has no issues playing files with Dolby audio as well as DTS so I just have it set to use that for all files now.
I would assume that Emby or Justplayer are using some hacky solution to get around the firmware reporting that DV is not supported which I know the Kodi developers have been trying to move away from using for some time now.

I uninstalled Kodi and installed that build now, restarted the tablet and started a Dolby Vision file - unfortunately i still have the same problem.
I will provide an adb logcat later, my tablet is not rooted so I have to install adb tools somewhere - after work.

Im connected with adb to the tablet, does anyone have good command to capture the right information from an external computer ?
adb logcat > log.txt gives too much and unreadable information.
Should I filter out only Kodi information ? and should it be filtered with only debug or error information ?

Hard to say. Check for stuff like: Surfaceflinger, Mediacodec and Exception. Should be "near" kodi's OpenFile print.
