HDR Image Support

Curious if anybody knows of any supported HDR photo file formats, such as JPEG XL or AVIF, or if they're coming any time soon. I have a photography YouTube channel and I think it would be really cool to include TRULY 10-bit HDR photos in my videos, since ACR now supports HDR photo editing. I've tried using .TIFF and other lossless file formats, but they don't retain their contrast or color depth, and require heavy adjustments in Premiere to get them to look anywhere near how they look after editing in ACR, and they never hit their HDR peak brightness for highlights.
