Exactly. They can change skyboxes, but not swap out names. Which ideally would happen sometime in the 2.X or right after 4.0 as an enhancement of a storytelling beat, but instead needs the slightly awkward write around for the enforced gameplay time bubble. And because of those hunting logs and FATEs, the mobs always have to be there. SB has this problem to a much smaller extent - fewer open world Garlean mobs- and they try to change the appearance of the most prominent castrum installation in the Overworld map.
