It's because you use the crackle pattern with a color_map that goes from 6 to 
zero over 0.03. With more samples, you follow the actual pattern more closely. 
There is about no difference if you go from 20 to 40 samples, so, yes, it does 
converge with larger values.
Want to shorten a bit more?
color_map{[0rgb 6][.03rgb 0][1rgb 0]}
is the same as
color_map{[0rgb 6][.03rgb 0]}
