Xbox Remote Play HDR issues with betas

Remote play changes the resolution and output for maximum efficiency and performance. That includes disabling HDR

So that includes the tv correct ?tv’s take a hdr hit in remote play ,Not the phone?

So I've been playing a few games on the pc Xbox beta and found an annoying issue with achievements while in HDR. I have HDR on in my W10 settings for games and apps, which there's no issue with that, works fine. Also I haven't had any issues with
the games on the beta or the game bar. What's happening is when I get an achievement pop up while I'm playing the game, it goes black screen then switches off HDR, back into normal then when the achievement bubble disappears goes black screen back to HDR.
It does this every achievement, which when starting a new game you get often. It basically holts all ability to play the game while its happening. Wanted to bring to attention.

I have the same issue with my PG35VQ, once an achievement pops it does the same thing, its game braking in Forza Horizon 4 when you're playing online and one pops, your race is ruined.

Any game with HDR this happens

You don't you take a performance hit when you use remote play on any platform including playstation

Hdr isn't possible with the performance hit

My issue appears to have just started yesterday.

AppleTV - Movies (Ex: Spencer Confidential) marked as DolbyVision and Atmos. Will play 2160p without issue.

PS4 - Example listed as HDR 5.1. Plays in 2160p.

XBOX ONE S is a recent failure within the past couple of days when Netflix tries to play a HDR and Atmos stream.

In XBOX ONE Example above appears as a HDR Atmos. All movies listed as HDR Atmos will not even start playing. Ultra HD 4K plays without problems.

No movie in HDR Atmos will play on XBOX ONE S though they did previously.

Definitely an update in XBOX but I have had no issues until Yesterday.
