No, the window is created by display-buffer, which is not obligated to
use it's action argument, e.g. if the buffer triggers a match in
display-buffer-alist.  

Maybe the documentation of delte-window should be amended, stating that
it is almost always preferable to use quit-window instead; unless the
window was created by using primitives like split-window.

Thanks,
