.hif to .heic for 10bit Standard definition editing

[jibbleton]

For some reason photoshop doesn't open .hif files on windows, however you can open them in lightroom. Here you can toggle a preview where you can see it with standard definition or HDR. When I convert with xnconverter to another format like jxl or avif or tiff, trying to maintain its 10 bit colour depth, it keeps the HDR viewing only. It looks very flat and it's difficult to make it look like the original photo I took. Is there a way of converting this so it can keep its 10bit profile but edit it for standard definition?

I'm using canon cameras. This file format is very useful because of the 10bit colour info, and the file size for transferring over ftp in-camera.

XnConvert convert to 8bits per component. You can try NConvert with tiff
