I was screwing around in The End, repeatedly died and hopped into Creative to fly back to the portal. Once I stopped and tried to travel back home through the overworld, multiple chunks in the desert around me had these chunks encased in darkness that acted like caves. Skeletons and the like are taking refuge in these areas, meaning it's truly being treated dark and not just a lighting error.
