This might be a MATE issue, I run both GTK2 and GTK3 in Mint Cinnamon and havn't seen theme issues. (default Mint theme, I'm too lazy to change it :) If by bookmarks you mean "recently used" then it definitely updates from both, but how accurately and how regularly I havn't examined in detail.
For Xfce dusk I can report the same as Steven does. Gtk3 applications running out of the box with some grayish stile. I put a screenshot to [1] to show what I mean.
