No Dolby, or HDR image with latest 4K Apple TV

I have an LG OLED TV (LG OLED65GX6LA) that supports Dolby Vision, HDR, HDR10, 120Hz but I can't get Dolby Vision and HDR matched with my new 4K Apple TV.

TV (04.40.70) and Apple TV (16.3) have the latest software versions, ultra high speed HDMI cables in place (also checked with “check HDMI connection”)

When de TV recognize HDR (HDR logo shown at right corner) no picture at all. Tried different setting without success.

Picture is present after disabling “HDMI Ultra HD deep colour” at LG menu but still no Dolby and no HDR.

Only black screens when I select “unverified formats” at Apple TV and returning to 4K SDR

Restarted both TV and Apple device after enabling Video and Audio > Match Content, however made no difference. Have checked the Apple support sites, is there anything I am overlooking?

LG Deep Color needs to be enabled, I have it enabled on my LG OLED and I get Dolby Vision. Not sure why don't get a picture with it turned on. On the Apple TV box I have Match Content - range & frame rate, and format 4K HDR

Is your Apple TV device connected directly to the TV? Is the HDMI port where it is connected to an eARC HDMI port

After enabling LG Deep colour, the screen turn black and I can't do anything. Match Content - range & frame rate are also enabled. Apple TV directly connected with high speed HDMI cable (I've tried different type of cables as well) to eARC HDMI port 2, but I've tried the other ports as well for testing.
