CZ walnut stocks run the gamut from gorgeous figure, to very plain. My 455 FS happens to have pretty nice figure, though my 6.5mm CZ 550 FS has much prettier wood. In contrast, my 527 FS is certainly a nice rifle, but the walnut is pretty plain.
I expect that keeping your eyes open for 452 or 455 in FS or Lux models will be your best bet, depending on which design you prefer.
