Let me comments and explains step-by-step:
1. You said:
"emacs -Q" session resulted in built-in latex mode
Yes. This is true in all my testings.
After the above step 1, I observed the following behavior:
2. If AUCTeX hasn't installed by `package-install', after I installed
it by `package-install' and open a .tex file, then AUCTeX LaTeX mode
will be enabled automatically.
3. If AUCTeX has already installed by `package-install', after I
re-installed it by `package-reinstall' and open a .tex file, then
*still* AUCTeX LaTeX mode will be enabled automatically.
4. If AUCTeX has already installed by `package-install', and I open a
.tex file immediately without reinstall AUCTeX, then AUCTeX LaTeX mode
will *not* be enabled automatically and the built-in latex mode still
will be effective for the opened tex buffer.
This is why it is necessary to test it using the following commands to
ensure that the latest version of AUCTeX is freshly installed for the
current Emacs session initiated by `emacs -Q'.
M-x package-refresh-contents RET
M-x package-reinstall RET auctex RET
