To be honest, no. I mainly know about JPEG XL only because I’m acutely aware of the limitations of standard JPEG for both photography and high resolution scanned documents, where noise and real world messiness cause all sorts of problems. Something like QOI seems ideal for synthetic images, which I don’t work with a lot, and wouldn’t know the limitations of PNG as well.
Ok so most monitors sold today support DDC/CI controls for at least brightness, and some support controlling color profiles over the DDC/CI interface.
If you get some kind of external ambient light sensor and plug it into a USB port, you might be able to configure a script that controls the brightness of the monitor based on ambient light, without buying a new monitor.
