There's a GTK3 release now, and as far as I can ascertain it respects the global dark theme setting. I tested this using:
GTK_DEBUG=interactive terminator -u
then using the Visual tab to play with the GTK+ Theme and Dark Variant settings.
I'm going to mark this as Fix Committed, unless I hear back that there is still some issue.
