No. Soul Stone do not transform anything into their most basic forms. Time can do it. Reality can do it. But Soul is exactly what it means - Control souls. It can manipulate them in all possible ways in can ever imagine, but reducing the universe into pure darkness is not one of it's powers. Only because it was killing her don't means that it is the Soul Stone, because the Orb also kill everyone who use it and doesn't has sufficient power to control it

I need to agree that transforming matter into dark matter don't prove anything because it can be done with sufficient energy and ALL the Stones emit some sort of colored energy, but, by the way, the ones who probably can do it is Reality and Power. Also, in the comics, these thing of "Reality Stone make your wishes come true" is an analogy. The Stone has reality-warping powers, thus, it can make everything you want. This is why everybody's wish comes true

The fact Malekith wanted to destroy the WHOLE UNIVERSE using it inclinates me to believe it is the Reality Stone. And in any place it was said the Aether required lifeforce to work. Malekith was perfect healthy using it. The fact is, as said in GotG, only beings of great power can use the Stones and Jane is weak, thus, she would die using it. And the Soul Stone do not required lifeforce to work. In the comics, the Soul Stone absorbs souls. If the owner negate it, then, the Soul Stone would absorb his lifeforce to sustain it's hunger, but, as long as Adam was feeding it, he was very fine
