Ok, thank you, maybe I'll give up and I'll definitely switch off the HDR untill also Kodi will be compatible
BTW, still don't understand while activating HDR on TV setting, Kodi will disable the 3D... Damn, this is a mistery!!!

Of course 3D and HDR won't work together as UHD/HDR specifications doesn't include 3D (in briefly reduced wording). There's no 4K or HDR 3D content either. Maybe there's some setting in the TV to set the HDR to "auto recognition", so it only will switch to HDR mode if detects a HDR input signal.

Edit: one more tip to add: Most TV's have the ability to set multiple different "Label Profile" settings to a HDMI source. So on the HDMI 1 Source, you can set the Label to "Game/Entertainment/PC" (differs from TV models) with HDR on, and you can set another Label with "Blu-ray/Cinema/Film" and meanwhile set HDR to OFF in the settings. I guess the TV should remember these settings for each Labels and change it  when you switch between the source Labels. Tho' you still have to switch between these Labels manually, but maybe it's more convenient.
