I think the granulation is due to the quality/editing of the photos. The carpeting below the coin looks similar, probably overly sharpened pics.
As for the Buff, nice example! Better than average for the date, especially that reverse! Obverse shows some typical softness for the date, some weakness in strike noticeable in the hair above the braid. Residual marks left in the hair are planchet marks not removed from strike. Small hit upper portion of the neck, small hit to the cheek. Carbon spot on the feather (no too worrisome but distracting). Bigger concern would be the spot below the jaw on the neck.
A few small hits in the fields below the belly, one on the left hind leg, one below OF.
Depending on how the luster looks in hand, if subdued, in combination with the two spots keeps it out of GEM for me. I'm at MS64, +/- 1/2 point if the spots can be dealt with.
