I don't know what metadata is shown by file->properties->details.

I think that FAQ 3 applies here.

But my guess might be that Windows doesn't support WebP metadata (I'm assuming that "file->properties->details" is Windows?).

This is the correct answer.

When you look at a file under Properties->Details, if there isn't already an blank entry there, then Windows will not read any of that data.  Here's an example


As you can see, the only data there is image size, file name andn path, FileCreateDate/FileModifyDate, file size, and owner.  Windows will not read any other data than this, no matter how hard you try.

If you compare that window to a jpeg file, you'll see there are a lot more details and you can edit them in that window.
