That's the point I'm making. You can buy expensive HDR displays that actually display correctly where it's not dark.
They're just expensive, and so most people aren't buying those ones.
So I will repeat, the problem is not with HDR content. It's with displays advertising themselves as HDR when they're simply not.
Spatial audio is like this too.
However, like HDR, it can be difficult to avoid. My laptop screen supports HDR because the laptop is otherwise exactly what I want and it doesn't come in a non-HDR variant. My earbuds support spatial audio because I elected to get AirPods Pro for their other qualities and they don't come in a non-HDR variant.
"Vote with your wallet" isn't really an option with things like this.
But, the net effect is still in the right direction, maybe.
Anyway I've listened to music mixed for Apple Music with "Spatial Audio" too and it sounds like crap compared to normal stereo mixes IMO so I guess my opinion stands.
Where do you configure "Spatialize Audio" globally? I can't find anything in the Bluetooth settings (where they've hidden every other AirPods config)
Somehow the transition from SDR to HDR has been messed up in a major way, for which I can't think of any similar equivalent. E.g. there was never any "step backwards" in going from 480p to 1080p or 4K, or from stereo to 5.1, or from h.264 to h.265.
But the rollout of HDR has been bungled catastrophically. The content is technically fine but the hardware side has been a disaster.
If I were the movie studios, I would seriously think about releasing 4K only in SDR until television manufacturers start showing HDR at full brightness again, and release software updates to fix it in existing models.
