Does the -A parameter even do anything when -k0 is set? From the manual it sounded like the -A parameter was dependent on the -k parameter being >0?

-k controls the degree of black point hue correction. -A controls the blend
rate between the fully corrected neutral axis and the 
black point. For -k 1, the -A parameter will do nothing because the black
will be fully hue corrected, so the -A parameter is only relevant when -k < 1,
and most relevant when -k == 0. This is all explained in the dispcal
