Anything else is bloat.
Not to mention the more tones and "realistic" color they add, the more jarring and out of place the saturated yellow skin on the minifigs feels. Also a friendly reminder that one of the reasons Lego quality is rapidly decreasing is that the expanded pallet made them switch from precolored ABS to virgin ABS that has color added afterwards(which also contributes to less standardized production meaning you're likely to get inconsistencies and slightly off-color pieces that were supposed to be the same color)
