Series X dolby vision still in testing?

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?

No, unfortunately, one cannot speak of clarity in this case, because I have experienced the exact opposite case.

I own the LG C1 and the LG C2, and the handshake problems have NEVER occurred in over a year of use on the C1! Instead, however, they keep coming back with the C2 on the same Xbox Series X console. When switching this console back to the C1, the same picture again, NEVER! LG C1 and LG C2 both support Dolby Vision (for gaming). Before testing the LG C2 with one / my Series X, I had never heard of the handshake issue with Dolby Vision. Besides, the LG C2 works very well, but the Dolby Vision handshake in games can hardly be tested on other devices, because the PS5 does not support this feature and other devices are at least unknown to me.

Of course the Blu-Ray disks I'm using are UHD and have Dolby Vision.

Dolby Vision is enabled on Xbox One X settings, TV HDMI ports are in Enhanced mode (4:4:4 4K/UHD HDR 60Hz), and the TV test (that can be found inside Xbox menu) returns all green ticks for my Xbox-to-TV connection.

As said, Dolby Vision works with all streaming apps... but not when playing Blu-Ray UHD Dolby Vision disks.
