In reality it's just that the output of the procedural generation routines doesn't quite match that of the primary simulation loop. A classic worldbuilding inconsistency.
Even if your observation were 100% correct, it's also 100% irrelevant to the point.
We still refer to Maxwell's theory of electromagnetism as a theory even though we know quantum electrodynamics is a more precise match to the primary simulation loop.
I suppose a few might have decided to rename it Maxwell's hypothesis of electromagnetism, but I would consider them crackpots or dilettantes with little understanding of the meaning underlying those terms.
