All these pix look fake to me. The blue one - the bezel is too big compared to what we've seen - and then like someone mentioned, the screen has this big black areas on the top and bottom.
The purple one doesn't look real to me either.. The trim around the camera and fingerprint reader looks colored purple - but doesn't Samsung usually keep that trim either silver or black? I mean even if you look at the blue one - you can see the rim around the camera is silver... (even tho I just called that out for being fake too, but you know what I mean)
Oh, also - the fingerprint reader on the blue one is on the wrong side.
