Alpha Skip Ahead Dolby vision not working anymore

"xbox not being able to play dolby atmos"

According to the Latest Alpha skip ahead Insider release notes this is still an issue the engineers are tracking and working on.

Hi

The Dolby Vision update has not be enabled yet (from my understanding) in the Skip Ahead build, but will be shortly.

It is still in test at this point in time. It may come out with the fall update, which has no release date yet.

In other words, as a simple user with xbox one x and compatible tv, I can't be using Dolby Vision until update?

ps Fall update - before december, correct?

If you're not in the alpha or alpha skip ahead preview rings in the xbox insider program you will have to wait, yes.

Microsoft has released a statement saying that Dolby Vision will only be available for streaming apps and it will not be supported by games. The Xbox Insider Alpha Skip Ahead team which includes myself just started testing it this week. Keep in mind we are
testing updates scheduled for release in 2019. Nothing more definitive and testing can change release schedule to the general public dramatically. And very few TVs support it. Samsung for example will not use it on any of theirs.

In the alpha skip ahead, still no update. "Alpha Skip Ahead" clearly means something else... :')
