Xbox One X Dolby Vision Gaming

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?

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.

Doesn't Xbox One x already support HDR10? Just waiting on dolby vision right?

I have a XBOX One X connected to an OLED LG C8. If I use the Netflix app on XBOX One X then the LG will display Dolby Vision. So I know that it is passing. But If I use a 4K Bluray that has Dolby Vision, the player will only output HDR。Blu-ray
playback is already up to date.

Yes, 4K HDR Dolby Vision works with the Blu-Ray player and NetFlix on the Xbox One X.
