Unfortunately, that has gotten more difficult in Big Sur8s Preview. It show the icon until you click the file name.

TexEdit keeps the old-style, as does Numbers, so I’m not sure what the preferred way is, nowadays, but I tend to move downloaded PDFs that way, so for me, it feels like it’s worse everywhere.

(Aside: looked at https://www.apple.com/macos/big-sur/ to see whether Preview’s new way is copied anywhere. That page clearly shows document based applications are becoming an endangered species)

That drove me nuts, but you can turn it off with a defaults setting. I don’t have it at hand but it’s easily googleable
