Garry, I haven't been able to find any pictures or info showing the Lutzow having that bow wave but I did find this passage. It's from that website I posted a while back. 
http://smmlonline.com/articles/kriegsmarinecamo/kreigsmarine.html"The black and white bands were 
usually combined with a section at both bow and stern painted in dark gray for a foreshortening effect with a false bow wave added in white or light gray. BISMARCK, PRINZ EUGEN, NURNBURG, LEIPZIG, 
LUTZOW, EMDEN and DEUTSCHLAND all wore this scheme at one time."
This only says that camo job "usually" included the bow wave. I guess absent actualy seeing a picture of the Lutzow with that wave you leave it off. I always thought it looked pretty cool though.
