The Safari is Internet Explorer for a new age.

And not work Edge too, Even if IE changes to Chromuim, it's still IE.

I’m not aware that avif can do HDR. Thanks, that’s great to know.

However, I tested on a few devices, support for it is pretty poor.

iPhone and ipad Developer Beta support avif,so this will be supported shortly.
But for some reason, Microsoft Edge is not supported for a long time.

Android also has support issues, and they are more serious.
But fortunately, we got full coverage on the desktop side. (The Linux desktop itself is working to add HDR support, and until that happens, it won't be considered)
