Sadly yes. It’s included by default in Apple devices and there are talks to bring it back with a Rust implementations. I think Google walked back a bit from their standard setting bullying practice with the antitrust lawsuits / threats of getting broken up. No idea if that will continue with the Musk administration.

Yes. JPEG is limited to 8-bit (which works well with rec.709/sRGB) and modern displays and cameras capture much more than that (typically 14).

sRGB has a very limited color gamut, and using a wider/HDR color profile (eg rec.2020) with only 8-bit per subpixel would result in colour banding.

I don’t want to limit my photo development with poor color definition.

Thanks for the links (I’m already subscribed).

Support JPEG XL or HEIC/HEIF and I will join ;)
