CD3 and CD4 produce different dyes with different hues and saturation. The E6 color developer is very much different than the C41 color developer even taking into consideration the differences between CD3 and CD4.
Most of the published formulas that I have seen for E6 and C41 are incorrect. You are lucky you got a usable image at all.
