I can reproduce this in Emacs 27.2, but not on the trunk, so it looks
like this has been fixed.  Here's my test case:

(insert-image
 (create-image
  (with-temp-buffer
    (set-buffer-multibyte nil)
    (insert-file-contents 
"/home/larsi/src/WebKit/LayoutTests/fast/css/resources/bikes.bmp")
    (buffer-string))
  nil t :format 'image/bmp))
