Show HN: I made an HDR ICC profile for JPG and PNG images
Sample HDR renderings (first few sample renderings): https://bsrender.io
The only viewer/platform I've been able to confirm it works on is the Chrome browser on M1/M2 Macs. It does not work on iPhone or Safari/Firefox on Mac.
The profile is derived mainly from saucecontrol's open source Rec2020Compat-v4.icc profile: https://github.com/saucecontrol/Compact-ICC-Profiles with 'cicp' and 'lumi' tags added. Since it uses the same transfer function as Rec2020, images will appear very washed out/fuzzy on unsupported viewers. I found this "bug" very helpful during testing as it was really obvious if the viewer was using the cicp/lumi tags or the (incorrect) transfer TRC.
With a bit more work you could implement something approximating the PQ transfer function but I actually like the 'you-know-when-it's-not-doing-the-thing' effect.
