As you have only just received it, you can return it either as unwanted, or as flawed (/broken). If you return it as unwanted, then you might have to pay for shipping, etc., but no questions asked. If you return it as flawed, they should refund you completely after they confirm the flaw.
But in the latter case, I would like to re-iterate what Baddass already said:
Is it REALLY representative of the real-life situation?
Keep in mind, you don't have to convince us, you'll have to convince the retailer/manufacturer. They will check the actual product, not the provided images. So if you want useful opinions, it is imperative that the images truly represent the real-life situation. Otherwise our opinions might only lead you to the wrong direction. Especially the fourth image (with the six thumbnails) strongly indicates that the images are more likely over-exposed/-saturated, therefore exaggerating the situation.
On the other hand, if those images are what it truly looks like, then it quite simply is a broken unit, and there is nothing to worry about. No retailer/manufacturer would dare to deny such an obvious flaw.
