I think this is readily noticed in imagery already out there, the edge is further refined past 4K. The scratch pattern on the bevel extends to the straightness of the edge, it is also visible in Verhoeven's micrograph of the 6K edge, and the improvement after the stropping. Some of the pictures I consider less than useful for hand sharpeners, as the appearance of the edge off the Tormek won't be anything similar to what you expect from unpowered hones and strops. There's a reason we use power tools, and the difference in finish on metal or wood after X amount of time from a belt sander and a sanding block with the same grit shows it.
