You got it backwards, it would be more beneficial in areas with few hours of sun for darker skin folks, since they do not absorb as much Vitamin D as fair skin folk do.
That comparison doesn't work. Only 10-20% of the vitamin D we intake is delivered through food and the body cannot process more sourcing from food. Even if you take more you will not benefit in an unlimited way, processing more. The skin is much better at generating/making/doing it.

It's my understanding that northern Europeans evolved fair skin in order to cope with the lack of vitamin D in their diet.

i understand it as: absorbing is in the intestine, generating D happens in the skin when exposed to the sun
