No. Sometimes stores have exclusive model numbers, but one model number is the same across all stores as well as on the website. (Yes, including HP)
LG isn't junk and this wasn't a wal-mart special so quality should be fine. This was just a black friday model that was produced for Christmas and sent to all retailers. It'll be off the street as soon as LG gets rid of the inventory it produced. Hopefully, it'll drop a bit more in price the further out we get from Christmas and I can snag one then. But for $800 I"d rather have the 55 inch Panny 55UT50 plasma that Costco is selling right now.
