Since TIF, JPEG, BMP, and GIF, it has been hard to get traction on new formats. Part of the problem has been related to patents. Part of it is the fact that the existing de facto standards seem to be enough for most to get by on for now. Another part is that every camera manufacturer has its own 'raw' format, largely based upon the silicon they are using for their image sensor, and that includes Apple's iPhones. Long ago, I thought that JPEG2000 might succeed JPEG. Nope. Some might blame that on lack of backward compatibility, but I believe it was for reasons not unlike JPEG-XL.
