-your pic doesn't show a powder blue label, but I'm guessing it is and it just the lighting in your pic.
I've noticed some color fading on some of my slabs, which could be due to exposure to light or something in the paper processing, where the color just didn't hold as well. The same sort of thing happened to some of my books' dust jackets -- the purple on the spine of volume 1 is but a pale pink now while volume 2 is as bold as ever. The same purple on the front cover, protected from the light, is the same on both.
The other checkpoints that BadDog noted are what I would focus on. Comparing to the link he provided, the only thing that gets me is that the alignment of the top row looks a little off to me -- the year/denomination row is closer to the grade row. The font in the bottom two rows looks only slightly bold/thick, but it's hard to tell at this size.
Edit to add: It's not impossible that even within a point-generation, PCGS tweaked their own template for spacing and such, or used a different paper stock. The finer points of the font (width of the "0", the loop on the "e"s, even the tail of the "9" slightly below the "1") look right.
