Interesting thought.
It reminds me of a conversation I recently had with a former elder who is now wide awake (I thought for sure he'd already been a long standing member here, but I was the one to make him aware of the whole ARC issue only a few weeks ago). After he watched sections of the ARC coverage that addressed the concept of "theocratic warfare", he postulated the theory that the GB knows the actual "truth" of things-- that it's likely Jesus died on a crucifix instead of a solitary stake; that Jerusulem wasn't destroyed in 607 BCE; that there's really nothing wrong with birthdays; that the sacredness of blood means it should only be used for the most sacred duty-- preservation of life. Yet, they see it as their justifiable duty to continue teaching "The Truth" (vs. the actual truth) because their job is to keep people's faith strong and keep them in the Organization-- even if it means they utilize "theocratic warfare" strategies with their own flock.
So for them, "The Truth" is whatever they see as most likely to keep the flock's faith strong at the time and keep them in the Org (pravda), not the actual truth on any one matter (istina).
