The advertised picture is just a vague representation, the preview on your character is what you use to decide to buy or not, to see what exactly they are offering. For example, on the game box, THE advertisement for the game, Satele is a attractive young woman. In game she's a weird black lipliner wearing, wrinkly old broad, who's gained 40 lbs. The advert is simply an artist representation, the prieview in the changing room is the exact representation what you're buying will look like on your character, and they changed it, its a bait and switch scam.
The images of content and armor on the cartel packs are in-game images, not some graphic cartoon hand-made drawing of an artist's "representation".
Get over it. The in-game was finally fixed to appear as intended.
