The short story is that I don't think you will be disappointed with the grain of your guitar in person, it's an absolute stunner. Here's a longer explanation:
The bookmatch is a regular old bookmatch. The only wood missing is the kerf of the bandsaw blade and the minor sanding to get things flat. Even though a lot can happen grain-wise in that small space, Quilted and Flame Maple don't really ever look bookmatched if you look closely. Here's some more pictures of your guitar.
This one is pretty straight on and with a flash:
If you concentrate on just a small area, you can see the symmetry of the bookmatch:
Enlarged for an even better view:
And again from a slightly different angle:
What shows up with the figured Maples is the grain direction. It's the changes in the direction that make the interesting and shimmery effect we all enjoy. When we slice across a plane, a given area of the left side of the bookmatch has the grain going up, while the same area on the right has the grain going down, but before we cut it, the grain was continuous.
It's sort of hard to visualize, but think of Les Paul guitars you've seen, with the Flame Maple bookmatched to center. On one side, the same shape of figure looks light in color, and on the other side of the bookmatch it's darker. Look at the back of this one on
Gibson's website and you'll see what I'm talking about.
