Dust under windows capactive button?

[Ruined]

I noticed a bit of dust under my windows home button if I look real close, anyone else experience this?

Maybe I didn't explain it right. My windows home button almost looks a bit "dirty," its not a solid white across the whole button. Is this some trange defect or something seen commonly on HTC smartphones. IMO not big enough to send phone back for (plus looking through forums far much worse stuff could be in replacement), I am just curious if this is typical to see.
