All I tried was `emacs -Q', then Dired, then `C-x C-q',
then evaluate (derived-mode-p 'dired-mode), which
returned nil.

I used Emacs 26.3 and 27.1.  Maybe the test you show
was introduced after 27.1?  Where do you see that test?

(FWIW, I can't imagine why `wdired-mode' would ever be
derived from `dired-mode'.)
