I tried https://github.com/karthink/org-mode/blob/olp/lisp/org-latex-preview.el#L142 and had an autoload problem: autoloaded org-latex-preview-process-alist requires unautoloaded org-latex-preview--dvisvgm3-minor-version in its default value, so just starting up Emacs raises an error:
;; top of the backtrace (void-variable org-latex-preview--dvisvgm3-minor-version) (>= org-latex-preview--dvisvgm3-minor-version 2) --- Dan.
