Context creates meaning. It is the combination of the four perspectives with the four domains that collectively describe and allow us to identify the nature of an inequity. You need look no further than the Dramatica table of Genres to see how combining perspectives with domains creates meaning. For example, combine the situation domain with the "they" OS perspective and you get a situation comedy OS throughline. If you combine the same perspective with the activity domain, you get a physical comedy OS throughline. Yet you need all four perspectives bound to the four domains to have a complete exploration of an inequity, which is one of the foundations of a Grand Argument Story.
So the true inequity of a story doesn't necessarily lie in one Domain or the other, but rather between all of them? In that case, an inequity can never truly be defined, correct? You can't say Well, the inequity of this story is injustice...You would need all four Domains to actually surround and approximate that inequity.
You are correct.
