I'm watching Pegasus now and at eight around 25 minutes in, there's an aft shot of the Enterprise in the asteroid field that appears to be CG. I don't recall this being mentioned previously.
Yup, it was originally stock footage from Booby Trap, which was replaced with the CGI model for TNG-HD. http://tng.trekcore.com/hd/albums/3x06/booby_trap_hd_305.jpg . That shot is seen again in Genesis too.
The CGI Enterprise is also seen replacing this shot:

But I think what hurts it is the feeling that it's just treading ground. We subsciously recognise that the show is finishing up, yet they're wasting what precious air time they have left on garbage like this?
