So upon further testing this is what's actually happening.
blueish:
redish:
When using the redish material map (thus a white specular texutre) the strength gets a lot stronger but in a very narrow angle (that's why I thought it was inverted but it's only visible in a very narrow angle)
So to anwser your question, both don't really do much when it comes to controlling the brightness of the specular texture, but rather the "hardness" of the light as I like to refer it to, very strange.
