Note that C-c C-c C-b (`TeX-fold-buffer') already folds the
environments in the way you expect (because it matches all
environments listed in `TeX-fold-env-spec-list'), I guess you refer to
C-c C-o C-e (`TeX-fold-env') or something similar.

I guess you refer to `TeX-fold-env-spec-list' variable.

I applied the fix you suggested, thanks.
