Does high melanin affect how light reflect from skin?Or there is no difference?

In terms of physics the surface is radiated by the light in the environment, it hit's the skin and is both reflected and absorbed and re-emitted elsewhere along the surface where it entered as refracted/diffused light, the split of how much light can be refracted at all depends on the remainder of light that wasn't initially reflected.
The reflective properties of your skin is due to the smooth surfaces of the dead skin flakes that makes up your epidermis.
The shape of the skincells does not change due to their melanin content so the reflected portion of light stays the same regardless of melanin levels.
Let's think of increased melanin in terms of a white person at the beginning of summer being pale as a ghost and getting tanned going darker towards the end of summer.
The untanned skin is not more mirror reflective than the high melanin skin but since it refracts a lot of the light and shows up very bright (white) and tend to drown out a lot
of the subtle reflective detail because enough light was sent our way as 'diffuse color' drowning out any subtle detail we may perceive in the reflection.
As the Melanin increase and skin turns darker less refracted light is coming off the surface as it's absorbed and the specular reflection that was always present
become more visible as it sits as light ontop a darker background.
So while the reflected light (specular/mirror light) doesn't change with melanin it's perceived contribution to the look of the skin goes up.
So if you want to create realistic looking skin it is more easy to get the correct look going if you author your shader looking at characters of different skintones.
If your reflection is dialed correct and you see the correct amount of ambient blues and whites reflected off your dark skinned character in a day-lit scene
while it simultaneously looks correct on your white skinned character you've made good skin shader.

Usually I save or download materials, because it might come in handy in the future.
This one, I really wouldn't need.

The sole reason for higher melanin skin content is ensuring light reflects differently. A white guy in the middle of Africa will cook himself without some SPF 50 because the sun's light reflects differently on him than one of the black natives

No but it definitely indicates in a statistically significant way the crime rates, parental abandonment, math skills, overall hygiene and watermelon consumption.
