I'm not saying it's logical, but I know CGI, and from all I can tell in that shot, it's CGId. Look at the snine on the surfaces. (Particularly above their head, and on the base of the wall struts) They're abnormal because the color of the surface isn't being reflective. In real life, a reflective surface looks somewhat transparent in that it's color shines as well. We don't have a shiny surface that acts as it does in that shot. It could possibly be a split second of perfect light, but from what I can tell, that's CGI. It's in the lucas style, too. Also note how sharp the background is. Unless they're using a very high framerate (Which wouldn't give any plus' to the movie, as the only difference would be slightly sharper backgrounds, which is a nono in cinematographe) the camera usually dulls the background when focused on the foreground. Particularly in that shot.
And the last shot is quite obviously CGI. The depth in it as well as lack of background blending shows that.
