HDR on Mi Pad 5 doesn't work as it should

[ImFIlippo]

Hi guys, I've tried to watch some movies with HDR (1080 and UHD movies) but the image is really really dark even on max brightness level in a dark room; I've tried both Plex and MX Player Pro but still nothing, even the HDR videos on YouTube are very dark.
Also I am sure that the HDR of the video works correctly because on a samsung galaxy s10 it works perfectly and I can see it very well.
Here is a comparison to show you the difference indicatively (S10 VS Mi Pad 5): Imgur Comparisons

Does this happen to you too?

My tablet: International Xiaomi Pad 5 with MIUI 12.5 (12.5.8.0 Stable)

I'm having the same problem. Dark scenes in HDR videos are completely crushed. I couldn't find a work around.

A lot of users reported this too, let's hope that xiaomi will fix it...

Having the same issue on mi 11 ultra. So seems to be a miui wide issue.
I tried disabling HW overlays, and it makes everything brighter, but dark and crushed blacks. With it on it looks good, but a bit washed out and too dim.
