I own this book in CGC 9.8.
These were triple-sized issues, so the "micro-tear" was a common production flaw due to the heft of the book. I don't think that CGC penalizes this flaw unless a small chip or flake works its way off the edge. Based on lots of experience (I own several hundred modern 9.8s, many of them with this flaw), it is my opinion that the micro-tear alone wouldn't keep the book from obtaining a 9.8 grade.
As for the recent pictures, while they are about as good as pictures can get, I don't personally feel comfortable guaranteeing a 9.8 book in this situation. I'd have to have a careful look at the book with my own hands and eyes. I can't call the first one, because I can't really see it clearly enough. If it doesn't break color, it's not a real threat to the 9.8 grade, especially with a professional pressing. I think I can spot the flaw you're trying to show in the second picture. Looks a lot smaller than the dimension you gave. At any rate, it's relatively small beans if the rest of the book is clean.
DISCLAIMER: CGC has been super, super tough (almost unfairly so) on 9.8 moderns lately. They seem to be very unforgiving. That's a risk you have to consider nowadays.
I'd feel comfortable saying that the grader did a good job grading the book as a NM. You got what you paid for. A 9.8 might be a different story. It's just to hard to say here with certainty. I don't see anything that would knock the book below a 9.4. The best wild guess that I can give you is 9.6, erring on the side of caution due to the recent flaws you uncovered. But the micro-tear? Not a big deal, unless CGC has radically changed their stance on this, which I seriously doubt.
