Yes, indeed it's a unconditional refresh. It does not match the meaning of word "toggle".
Seems need to detect whether has image overlays in region. I added this
detection in new patch. Like bellowing:
#+begin_src emacs-lisp
...
((use-region-p)
(if (seq-contains-p
(mapcar
(lambda (ov)
(plist-get (overlay-properties ov) 'org-image-overlay))
(overlays-in beg end))
t)
(progn
(org-remove-inline-images beg end)
(message "Inline images in region removed."))
(message "Displaying inline images in region...")
(org-display-inline-images include-linked nil (region-beginning) (region-end))
(message "Displaying inline images in region... done.")))
....
#+end_src

About the INCLUDE-LINKED argument, I don't know how to process it. In
theory, it should be handled by function org-display-inline-images
instead of org-toggle-inline-images. If you have improvements on it, can
you add code on my patch?

Refreshing all image previews in buffer is same as old behavior. My
patch's purpose is to improve function org-toggle-inline-images behavior
which refresh only in current level scope instead of whole buffer with
lot of inline images especially heavy and suspend Emacs. Because
function org-toggle-inline-images is used in of lot Emacs ob-* related
packages on after babel execution hook. Old behavior caused execute one
source block need to refresh whole buffer all images. Instead of only
current headline images, or just results image.
