Ok, now I know you are talking nonsense. I modded my Skyrim since release and I really know much about the structure of the game. Textures and mesh path and I can assure you that the DLCs where not on the disc! Sure a Vampire that has been reused is on the disc but the new parts the castle as an example is new! Take a look at the base files and extract them and you will see. So please stop talking about things where you have no knowledge, at least for Skyrim I can say you have none! Also, the DLCs for Skyrim are several GBs of data not just key holders like the Screenshots in the opening post show. And again proof us what you say or at least explain how you came to this conclusion we all wanna know.
