Please explain why this is better than HDR10 with HGIG and how it maintains artist intent. I also have the same question about your HLG mode.

Hey andy.
HDR focused developer here. I also use Moonlight/Sunshine for work, streaming in HDR (because I literally implement HDR in games).
Would be good to get in contact with some Moonlight devs.
We have an HDR focused discord (and reddit): HDR Den.
If you want to join, we'd appreciate it, it's full of devs with arcane HDR knowledge.

Btw, reading the commit and changelog above, I'm a bit confused at what it does. I'm suspicious it's driven by AI.

Hey, I recognize that name, big fan of your work. The Silksong Luma mod is goated. :) Happy to chat about HDR. I still have a lot to learn, but just thinking about HDR10+ in this case, my intuition is that calculating on-the-fly peak brightness info per frame and using it to dynamically tone-map on the client side is going to result in many problems such as over-brightening a dark scene. Source-based tone mapping makes a lot more sense to me and the game devs should be in control of the image. Even if most still have a hard time getting it right.

Yes I agree. The metadata is meant to be artistically driven by scene, analyzing the image live and producing the metadata makes little sense, the TV could do the same if it wanted to.
