I'd say the stickers if anything are worth less than they were before. All of this is gimmickry - purple label, PWCC AA, E, whatever. As TPG grades supposedly consider only the physical condition of the cardboard and not necessarily eye appeal, stickers like this were originally just another stamp of approval that "Yes, this is a PSA 5, but it's a damn GOOD looking PSA 5." Ok, whatever. Given that the 5 itself is just someone's opinion and not an end-all, be-all pronouncement of value and card bragging rights hierarchy, how is a sticker any different?

To me these things are interesting, but unnecessary. Kind of like ebay re-authenticating cards already in PSA and SGC holders and then putting them in a neat little blue box to make them seem more official. It's largely a waste of time.
