HDR Streaming with Disney+ on Safari

After getting tons of blooming and no peak brightness I realized that my content is not streaming in 4k HDR. I have searched all over and see nothing about this topic. Disney+ claims to automatically play at the best quality where Safari claims to support HDR. So what am I not doing correctly? Battery setting is not set to “optimize video streaming while on battery”.

I have been watching shows on my iPhone 13 Pro since I do not have a tv, and now that I finally was able to upgrade my computer I was hoping this would be a better viewing experience than my phone..

Any help would be appreciated!
