Maybe. If we are only talking about "revealed truth" for the moment, two factors come into play: how much is being revealed and how much of that can be understood.
If we ignore for now what the nature of god actually is and just focus on the assumption that Truth can be revealed to humans, then first some or all of that Truth might be revealed through a particular source. At the receiving end, some or all of what was revealed might be understood/experienced. At the receiving end humans might not be capable of grasping all of the Truth or might well be very capable of misinterpreting what is revealed. Humans might well infer intent or purpose where there is none. And different people may have differring capabilities for understanding what is revealed to them.
The measure of incompleteness may be at the sender side, but it is more likely at the receiver end.
