Why is it even an issue, do both images in the infobox make it take longer for the page to load or something?

As "anal" and mental as it may appear to you, coloring of the characters is important. For example, imagine that one day Kishi would have shown us Killer B's hypothetical family and all of them with white hair. The anime would presumably draw them with white hair too, save Killer B of course....

Hair and eye color can tell a lot, like blood relations and so on. Also it's important for stuff to be shown and told as intended by the author, foremost. And yes, coloring is a difference major enough.
