Void seems a most inappropriate word.
Void to me suggests empty. Less dense is hardley a void.
I have wondered about their dark matter content..could there be more dark matter or less.
I could suggest support for either however I wonder what observations will show.
I wonder if voids are expanding or collapsing.

Physicists have already measured that the so called "vacuum" of space isn't really devoid or energy or matter. It exerts a pressure, and is measurable. Quantum particle pairs emerging from nothing, and then combining to completely vanish back into where they came from is a very spooky thought.
Perhaps the term void doesn't make sense in any context whatsoever unless it is stated what the volume of devoid of.
I agree with you though, I would have referred to this region of space as sparse or even a dessert rather than a super void. (and if it turns out that 3/4 of the Universe is indeed comprised of Dark Energy, which cannot be detected directly, then what does this term "super void" really mean?"
