If you mean prettified (in terms of prettify-symbols-mode) by "nicely
substituted", then you can simply add the missing replacements to
`tex--prettify-symbols-alist' (provided by the standard emacs
tex-mode.el which auctex simply re-uses).

However, note that prettify-symbols-mode only supports
string-to-character replacements, so replacing \mathbb{RR} with ℝℝ won't
work.
