I discussed this with Andrea Cimitan a few weeks ago. He showed me that the reason this isn't properly fixed yet -- title bars and toolbars are still almost identical for focused and unfocused windows -- is that while GTK can now change appearance when focus changes, it is currently quite slow at doing that. So a window's title bar changes color when it gains/loses focus, and then the toolbar changes to match a fraction of a second later, which looks uncoordinated.
So the next step to fix this problem is to make GTK faster at changing its focused/unfocused appearance. Then the theme can increase the difference between those appearances.
