I don't think you'll get a new one for seven stuck pixels. Sorry. There's a set ratio that Apple uses to determine when a display is bad in terms of stuck/dead pixels. I can't remember what it is, but I think you'd probably need more than seven to qualify for a new one.
Another technique to get them fixed is to make a movie with lots of different colours which change very rapidly (use PowerPoint if available). Leave this running in the same area as the stuck pixels overnight and sometimes pixels become unstuck.
