Version 9 themes not available for existing project

I have a project that I’ve been updating for a long time. I decided to update the look, but do not see any version 9 themes available. Only old V6 and V7 themes. The install has been updated with the online updater. I do see that if I create a new project it uses V9 themes. How do I get the V9 themes so I can apply them to an existing project?

I may have figured this out. I created a new theme and it used V9 Rhino. Is there only one theme for V9?
