I'm not sure how accurate my spectro is in the very neutral area, but those Lab A values look lower than most, but it might be my spectro that is reading high.  In general, among the papers I use, I tend to like a somewhat relatively elevated Lab A.

There are some interesting dips on some of those graphs.  It makes me wonder what is in the paper or coating that is absorbing light in a narrow band.  Interesting stuff, but a bit hard to relate to on first exposure.
