Indeed, there is a similar purpose function:

#+begin_src emacs-lisp
(defun modi/lower-case-org-keywords ()
  "Lower case Org keywords and block identifiers.

Example: \"#+TITLE\" -> \"#+title\"
         \"#+BEGIN_EXAMPLE\" -> \"#+begin_example\"

  (interactive)
  (save-excursion
    (goto-char (point-min))
    (let ((case-fold-search nil)
          (count 0))
      ;; Match examples: "#+FOO bar", "#+FOO:", "=#+FOO=", "~#+FOO~",
      ;;                 "‘#+FOO’", "“#+FOO”", ",#+FOO bar",
      ;;                 "#+FOO_bar<eol>", "#+FOO<eol>".
      (while (re-search-forward "\\(?1:#\\+[A-Z_]+\\(?:_[[:alpha:]]+\\)*\\)\\(?:[ :=~’”]\\|$\\)" nil :noerror)
        (setq count (1+ count))
        (replace-match (downcase (match-string-no-properties 1)) :fixedcase nil nil 1))
      (message "Lower-cased %d matches" count))))
#+end_src
