I doubt it's altered after giving it a look. My best guess is there's a "fatal" imperfection that wasn't picked up during GAI's grading process. It's probably known and was either a previous crossover attempt, or one that was obvious enough to avoid trying. The thumb sized dark spot on the back (very top) could be one such issue. Hard to tell if it's staining or more. There could be a bit of paper loss somewhere too.
