Xbox series x . Dolby vision gaming

Hi I have a Xbox series x with a Dolby vision compatible tv also will the allow Dolby vision playback selected in settings on and it still only displays in HDR only when playing 4k blu rays ? I have set it 4k 60hz and the games display in Dolby vision plus streaming apps but not 4k disc playback! Is this correct that the xbox series can’t do this ?

I do know about the gaming part. I was asking the question if the Xbox Series X could have the Dolby Vision added into the BluRay app so, that 4K BluRay movies can enjoy Dolby Vision as well.

I have a series x connected to a Philips Amerlight 65pus8535 I get 5he silver metallic screen playing x/s dedicated games and it also appears while using Disney plus app from my tv apps! Is this a problem with my tv or is it a Dolby vision problem, I have turned off the dolby for gaming and this worked but in the detail list on my Xbox series x it says that the dolby vision may experience distortion?

Greetings.

According to this:

Dolby Vision available for Xbox One S and Xbox One X in interaction with Netflix app.

My question about Dolby Vision support on Xbox One X for two games from Dolby Vision list:

Can You, please, answer my question?

I got a response from Customer Service: no support for Dolby Vision on Blu-ray app on Xbox One X at the moment (not even on Xbox Series X).

They said they are working on that, since a lot of people made complaints about this issue. I hope it's true, it's ridiculous to not support Dolby Vision nowadays on a device that has been promoted as a valid Blu-ray player.
