Since all common worlds have Jungle, Ice and Hallow Biomes, these three chests are guaranteed in your Dungeon, but since one world only have Crimson OR Corruption originally spawned from the world's generation, only one chest themed by your world's infection will spawn in the Dungeon.

To obtain the other infection's chest, the player will have to create other world, trade with other player or even use a Inventory edit.
