Completely agree. To me, HDR feels like the system is ignoring my screen brightness settings.

I set my screen brightness to a certain level for a reason. Please don’t just arbitrarily turn up the brightness!

There is no good way to disable HDR on photos for iPhone, either. Sure, you can turn off the HDR on photos on your iphone. But then, when you cast to a different display, the TV tries to display the photos in HDR, and it won’t look half as good.

You might be on to something there. Technically, HDR is mostly about profile signaling and therefore about interop. To support it in mpeg dash or hls media you need to make sure certain codec attributes are mentioned in the xml or m3u8 but the actual media payload stays the same.

Any bit or Bob being misconfigured or misinterpreted in the streaming pipeline will result in problems ranging from slightly suboptimal experience to nothing works.

Besides HDR, "spatial audio" formats like Dolby Atmos are notorious for interop isuues

On both Android & iOS/MacOS it's not that HDR is ignoring your screen brightness, but rather the brightness slider is controlling the SDR range and then yes HDR can exceed that, that's the singular purpose of HDR to be honest. All the other purported benefits of HDR are at best just about HDR video profiles and at worst just nonsense bullshit. The only thing HDR actually does is allow for brighter colors vs. SDR. When used selectively this really enhances a scene. But restraint is hard, and most forms of HDR content production are shit. The HDR images that newer iPhones and Pixel phones are capturing are generally quite good because they are actually restrained, but then ironically both of them have horrible HDR video that's just obnoxiously bright.
