Theme blogs.mu css differences from demo and actual install

I have include two screenshots from an fresh install (1.2.9) and the demo of the blogs.mu theme. As you can see there are 2 areas that different from the demo.

Those are the default settings without any modification.

1. The gradient effect is not anymore following the menu bar. (just grey solid color and the text color is also not the same )
2. The space between the groups and service area is now too big. It is missing the background effect.

Is it possible to make these CSS changes to much the demo, or provide me the demo's css files so I can apply them providing they are compatible with BP 1.5.

First option is preferable for future upgrades..

Thanks in advance
