The default implementation has more than 1000 more dynamic than the human eye or the best digital movie theaters. It would be possible to compress the highest quality photography with JPEG XL without introducing quality problems. Likely you get 1/5th of the file size from EXR -- smaller file sizes can improve some web based workflows -- for example when an advertising team is distributed, or partially in work-from-home mode. Bringing the quality of professional photography to the masses is another thing. Today, mobile phones rarely have too much capacity and many users are fighting with their memory space getting full. There, uncompressed or poorly-compressed formats are not a realistic or cost-efficient option.
