Correct, the "background shader" is currently not reflected. This will be fixed, of course.
The current method of handling stars through noise shaders would not provide for lighting when you are closer to a particular "star" in any location, of course. It is merely a 2 dimensional effect. TG2 is not a galaxy simulator so such 'real star' functionality is not likely to be implemented any time soon. If you wanted local stars contributing to lighting, simply create new suns or light sources. The star background effect is really all that is needed for most cases considering the tremendous distance between stars.
