You missed my point.

Any application can get the thumbnail JPEG from the EXIF data of any
file, even if it can't read the contents of that file. That's why the
thumbnail is there.

Photoshop *could* be showing you this EXIF thumbnail in the open file
dialog. That wouldn't mean Photoshop can actually open the file, or that
it's using a plugin to show you the thumbnail.
