JPEG-XL allows the use of client-side synthesized grain. A method pioneered by Netflix/AV1 I believe. Compression algorithms struggle with high frequency detail, which often introduce visible artifacts. JPEG-XL allows to decouple the grain component from the actual image data. This allows for significantly more efficient compression of images that inherently require noise, such as those in gnome-backgrounds — smooth gradients that would otherwise be susceptible to color banding.

So basically dithering is on its own separate channel?

If anyone is wondering, you can download the .jxl files from here:

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
