Dolby Vision for Minix U22X-J (Max) and Ugoos AM6+

OK, decided to test DV on my AM6B+ again with 20.3 version.
First online update to “normal ng” 20.3 - OK.
Then based on error message I have uploaded empty “.nocompat” file with the new “CoreELEC-Amlogic-ng-dv.arm-20.3-Nexus.tar” file to /storage/update folder and restart.
Update went OK as usual, CE loaded fine.
Only issue was that my Sony TV input has changed to another active source (VU+ receiver) so I had to turn off the receiver to get back to CE.

CE is reporting the AML-NG-DV.arm architecture + all plugins are working, good.
Compared the boot files (kernel,system,dtb) size/dates via putty with .tar files and all is the same.
Checked DV related settings - needed to activate “Player-Led” because my Sony TV doesn’t support TV-Led (LL-only model).

Then started to play LG DV videos - DV logo on the TV activated but colors are garbled (green-violet tint).
Changes of "/Player/Videos/“Convert DV…” to any available option haven’t helped to fix the DV color problem.
The same videos play with correct colors when played via Android/Kodinerds version (but choppy). Ugoos is on the latest firmware and with DV-LL Enabled(YUV) + Adaptive HDR mode. TV ColorSpace/HDR mode on Auto.

Anyone else out there with Player-Led TV having color problem with DV videos?
Any CE options to check/change?
