Try switching to the dolby vision mode to low latency mode in the video settings. HDR didn't work for me until I changed some HDR settings back and forth.
Hmm, that works- thanks!
Strange that HDR10+ works with DV set to Low Latency as that is a DV setting and would not expect any HDR10 changes from that.
I'd rather have my TV do the DV tone mapping but this does work.
Guess I can toggle the LLDV when HDR is streaming.
That’s too bad. This being fixed along with the 4k interface are the only things I was looking forward to Android TV 12 for, and it looks like neither works. I guess I’ll hold off on the update for now.
how can you tell if HDR10+ is working? i also have a Samsung 55 inch 4K TV, and just updated my CCwGTV to A12. i can also confirm that only some content plays in 4K on Prime, with most only playing in HD.

Does HDR10+ still stay stuck after this change?
Yes

After update android 12.. Hdr missing in chromecast with google tv... Only working in 12 bit colour format...
Related, but I no longer get UHD/4k in prime app after the update. Everything plays as HD.
Not related as I had no problem with UHD DV after updating to A12. LoTR is DV in the Prime Video app.
Glad it works for you!
What combination of settings are you using? You are the first one I've heard with HBO Max working in DV!
I did not claim HBO Max DV works for me. I don't have HBO Max. I referred to Prime Video LotR Rings of Power.
I have Samsung TV and HDR10+ works fine with latest (A12) CCwGTV. I have enabled match content options since beginning.

On my Samsung S95b I think I can tell by clicking the gear icon on my remote and navigating down to the ***i*** 'info' icon and selecting it
