Decolouration Plastic

[Confused]

Anyone else's Phantoms affected by decolouration on the ring just above the midrange unit? The white plastic is turning slightly yellow/brown on mine. Seems like some sort of heat decolouration 

Heres the new phantom no questions asked warranty.

Wonder if discolouration is considered not up to their standards.

So far my phantoms stayed very white even with sunlight hitting it but with the number of people complain about this there might be a lot of returns with this new warranty package.

I notice that it's a hardware guarantee, with the software you take your chances!
