Depth. Wider color gamut, HDR, the things our devices now capture and render. And it supports animation by default, so the "motion photos" will be natively shareable. Also, recompressing JPEG as JPEG-XL gives a free boost, so simply, why not. If you're sharing something in social media or anywhere, there is no reason to not convert and have the other person receive JPEG-XL by default. My point is less about the size and so on. But what the visual (bit depth and color gamut) and functional leap of JPEG-XL. It's a format that combines and replaces the many different use cases that different formats are doing now.
