Some physicist once said "I endeavor to never write more clearly than I think"; in the same way, history probably shouldn't be presented more vividly than it's understood. (We already have this problem with people remembering incidental details and emotional vibes from historical fiction as if they were established historical fact; VR diffusion delusions would make this much worse.)
If you read actual history the historians typically go into quite a lot of depth on why they think X happened as opposed to Y, and what the limitations are on the theories and the reasoning. The amount of archaeological and written records we have is very important to those facts.
