Being a CG student, I know that when done right with Live Action, CG looks amazing. It seems more that she has added some CG for that touch of fantasy, as she said, but it's not all CG. It could be just certain aspects of it are CG, but not full on like Whatchu Waitin On? (which was also very well done), or it could just be some special effects added in, or some scenes are CG and others not. By luxurious she could mean they do actually have some pretty nice, elaborate sets going on, like the stage on in the PV image preview, that didn't look CG.
