Yes (though you likely already figured)

Did you check whether those files are invoked at all by cinnamon?
xinitrc is related to xinit which is used by startx, but desktops tend to operate on their own stuff (eg. startkde doesn't read ~/.xinitrc at all, you would have to explicitly add it to its autostart stuff.

I know nothing about cinnamon nor Mint, sorry, but if cinnamon-session is (typically) a script, you might find its inclusions there (otherwise best ask cinnamon developers)
You could also start a bare X server, xterm and "strace cinnamon-session 2>&1 | grep open" to see what files it opens (iff cinnamon-session is an ELF binary!)

I bet that cinnamon-session ultimately re-sets the xrdb (as does KDE on starting up)
