In the case of birds that have sexual dysformism, is it possible to notice it by illuminating them with blacklight?

In my case I have a cockatiel (Nymphicus hollandicus) which is a lutino. They do not have a visible sexual dysformism due to their color, but when I illuminate them with black light I see points under their wings and lines on their tail.
