Yes, you're missing a change introduced in AUCTeX 11.89
(https://www.gnu.org/software/auctex/manual/auctex.html#Changes):

    Indent ‘\[...\]’ math mode as a regular environment by default.

In order to easily insert \[...\], I'd suggest you to set
`LaTeX-electric-left-right-brace' to t, I find this very useful in
general.

Bye,
