HDR not working properly

[PrithwidipSaha]

Hello... don't know if it's the correct thread to discuss on this topic still I'm trying my luck...I have a Xiaomi 11T Pro which has HDR10, HDR10+ and Dolby Vision support. Recently I got a chance to watch few HDR videos on my friends iPhone 15 and I noticed that its very different from what I see on my phone. I tested a video that is https://youtu.be/LXb3EKWsInQ Here in the very first scene I noticed that the clouds on the left has so much details in them which is not present in my phone. Mine just blows the highlights. I even downloaded this video and played it offline through Just Player and MX Player and I got the same results, highlights are blown and shadows lack details and this is happening with many other videos I tested. I even changed the display color scheme from standard to vivid and got the same results. Right now I'm at loss, I realised that for the past year and a half all the HDR movies and videos that I have watched wasn't properly displayed on my screen. What I want to know is whether there's a fix for this? Is it a hardware issue or is it something else? How can I get my phone to play HDR videos without blowing out highlights and properly display them. Also when I play HDR videos be it offline or on youtube my display gets slightly bright and it turns yellow. If anyone knows any workaround please help
