All 4K HDR captures are rendering 4K SDR on Series X

I have the xbox one x with a 4k tv it does take the 4k hdr pictures its just when they upload to my phone or twitter it looks like the sdr version and not 4k hdr

Thank you for your answer, but I think you did not understand my question. To sum up: 4k doesn't matter.

The problem is that hdr blu-rays work fine on ps5 (good colors).

So the HDR to SDR conversion is correct. But on xbox series x, in comparison with ps5, the picture is too dark.

So the HDR to SDR conversion on the xbox series x is bugged. I don't think it's a washout color issue.

Since my TV does not support HDR, I cannot activate it and it is disabled by default.

As I really like Interstellar, it was offered to me in 4k without knowing that I do not have a 4k TV.

What I mean is Xbox series X has a very dark image with HDR blu-ray. But when I watch HDR blu-ray on my PS5 I have no problem.

I think Xbox series x is not converting HDR to SDR correctly but that the ps5 yes.

On the other hand, blu-ray 4k comes out very well on a 1080p TV.

I know the problem exists in both 4K SDR and HDR. I haven't experimented with 1080 capture and probably wont use it as it doesnt look good and captures at 30fps which is also weird.

thanks I saw that QUEENMISFITS. however that's the post i used to get to where I am now. it did not solve the issue for me that I am facing and in that article it states

"On the Broadcast & capture screen, select "Game clip resolution" then select 4K SDR, or 4K HDR. 4K SDR will record videos in a standard colorspace, while 4K HDR will record them in High Dynamic Range,
making them viewable in full detail only by those with HDR-compatible TVs."

So it explains a little about the difference between 4K SHD and UHD color space but not why the saved file is coming out as 1080p when my settings are clearly set to 4k.
