Those limbs look like they'll kill deer just fine. "Amateur flash close-up photography" is synonymous with "that looks terrible."

If you are just taking a casual picture, flash brings out the worst in everything. It is very tricky to take a good photo indoors, that close, with a camera-mounted flash, so cut the guy a break.
Flat black won't match the appearance of the original camo finish because it is a different process. However, it's doubtful you'll have to worry about cracks and flakes ever appearing in the finish of these limbs.
So, yes, these pictures are anti-climactic to those hoping for more, but reserve final judgment for when you have them in your own hands on your own bow.
