Hold on a sec.... Am I understanding this correctly? If I set my Apple TV to sdr 4K it will display everything in sdr, but Will still display hdr if hdr content is played? If this is true, I’d much rather have my atv work this way because the ui looks washed out and colors are exaggerated.
Got a tip for us?

Are you using ATV Match HDR/SDR & Frame Rate settings or defaulting two months on?

I run mine in 4k SDR and enabled matching.
When I play a DV or HDR movie, it automatically switches to DV or HDR to match the movie range and frame rate.
I used to have Dolby Vision as an option now I don't I just SDR or HDR how do I get Dolby Vision back please?
I will switch automatically to Dolby Vision ONLY when it senses a Dolby Vision film.
The ATV UI is in 4K HDR - not Dolby Vision.
IF you want EVERYTHING - SDR etc to be played in Dolby Vision, then you have to switch Match OFF and select the option such as 60HZ Dolby Vision.
I'll have to try this out this weekend. This whole time I had it set to 4k HDR thinking that was the setting I would need in order to actually view any HDR content. Thanks!
Actually thats not quite correct. HDR originally has a fixed metadata for each set scene for contrast/colour etc, where as Dolby Vision has a dynamic metadata so it can be continually adjusting contrast per frame if needed, which means the accuracy is better. What HDR10+ does is add dynamic metadata so it produces a more accurate contrast and colour gamut to bring it in line with Dolby Vision, although there's is a lot of debate about that in the industry.
The main difference is, as you say, that Samsung are involved in this new flavour of HDR, but unlike Dolby, who charge manufacturers around $3 per TV set for licensing, HDR10+ is open source and is free.
And don't forget HLG, this has been developed as it's far better suited for broadcast purposes. Both SDR and HDR are transmitted on the same stream, which is 10bit HEVC, which makes it easier for TV, and the data stream is way smaller than full blown HDR. It's not as accurate as the other two HDR's, but way way more stream lined. Having enjoyed quite a few World Cup matching in HLG this summer, it gets a massive thumbs up from me
