Like CFTBL the center is protected by the plastic window and if it's like CFTBL and there are really zero airballs and it plays a little slow then yeah... you won't get many/any dimples.
My Creature doesn't have any dimples either but that is because the balls never leave the PF...just roll around nicely. NOT because it has some kind of super wood or something.
That said my original MM developed a shallow elegant "orange peel" over the years. Not like the deeper, almost cratering effect we see on some of the newer machines. Because it's an organic product the density of wood can vary greatly.
