Question for Cyan/White Lumia 800/900 owners

Has anybody with a Cyan phone notice the color becoming discolored overtime?

Has anybody with a White phone noticed dirt getting trapped in scratches and becoming visible?

I ordered a Lumia 900 from AT&T but they only had black in stock so that is what I will have when it arrives, but I am thinking of exchanging it at a corp store for a cyan or white model.

This review from cnet has me questioning the discoloration of the Cyan model(Skip to 3:15): http://reviews.cnet.com/smartphones/nokia-lumia-900-cyan/4505-6452_7-35178153.html

Also I stumbled upon this video on youtube and the cyan Lumia 800 appears to be discolored: http://www.youtube.com/watch?v=sQx8THOpVLo

The white Lumia 900 unboxing at WPCentral has me questioning dirt getting into scratches and making the phone look bad: http://www.wpcentral.com/unboxing-hands-glossy-white-nokia-lumia-900-att
