Unless they're already done shaking the crap out of it (after all sometimes static frame tests are completed before flight tests start). Then it would be sitting around in retirement somewhere...The static test airframe should still be rigged to a airframe stress simulator having the living daylights shaken out of it.
As for lighting, well I do not remember ever seeing any sort of lighting that can make a dark material look many shades lighter in nature.
They either re-painted it, or this is another airframe, either a mock up, or another flying prototype.
We should know more soon.
