There’s also data that isn’t needed in the final delivery format but is needed for editing. 8bit vs 16bit color for example. 8 bit is visually all you need for an image, but if you edit it to say being up the shadows, 8 bit will show banding because you’ve stretched it to the point the bands are visible. While 16bit has so much extra data it still looks perfect after being stretched.
JPEG XL is the ideal high end photography format. AVIF seems better for a space efficient web format.
