With the new folding signature support, you can achieve the desired
effect using either
;; At most 1 args.
(setq TeX-fold-macro-spec-list
`((("⬖ {1}" . 1) ("begin"))
(("⬗ {1}" . 1) ("end"))))
or
;; At most 0 optional, 1 required args.
(setq TeX-fold-macro-spec-list
`((("⬖ {1}" . (0 . 1)) ("begin"))
(("⬗ {1}" . (0 . 1)) ("end"))))

Another approach here would be prettification, assuming you're OK with
specifying each environment. I use something like:
(with-eval-after-load 'tex-mode
(mapc
(lambda (sym) (add-to-list 'tex--prettify-symbols-alist sym))
'(("\\begin{equation}" . ?↴)
("\\end{equation}" . ?↲)
("\\begin{align}" . ?⌈)
("\\end{align}" . ?⌋)
("\\begin{multline}" . ?⎧)
("\\end{multline}" . ?⎭))))
