These "rich darks" areas are more likely to be related to high total ink rich
black-type formulations then Maximum Chroma in the sense of highly saturated
bright colors. Whether these blends are mathematical illusions, or whether
they add significant richness to the dark tones of appropriate images is the
first question. If they add little visually, then they are not worth pursuing. If
they do, then you may want to make the effort of determining the best
ink-limiting/ linearizing/ black generation/ profiling combination to obtain and
control them.
