There is always a lot of hype before a bag comes out and then everyone wants to buy it first chance they get. The people who want to buy the bag have certain expectations about what color it will be IRL, what the texture will be, how it looks on them etc. When the bag arrives and it doesn't match up to their mental image of what they thought the bag would be, then yes, there are negative comments by the OPs of threads about how they are disappointed the way the bag looks.
Instead of getting upset about it right now, why don't you wait and see? Then if you truly love it, buy it, model it and it would maybe change the minds of tPFers who thought the bag didn't look nice. I've changed my mind on items after seeing great modelling pics!!
