Ok, again
PS4 Version -> old version (+Pro), with many big packets.
PS5 Version -> just the PS5 Version. Textures and other assets etc are just in the package that are used for that version. This only runs on PS5 and not PS4 Systems. Maybe it even uses the compression hardware of the PS5 as native PS5 game it can do such things.
Xbox Version -> Contains the xbox one, X and Series X Version. Packet as a normal xbox one would use it, just other code-paths implemented to distinguish between the versions. A real next-gen only version would have been broken up into smaller parts, that just contain what is needed. They could have gone the way to put out different versions for each console, but they went the way to pack everything into one version.
Btw, the PC Version of control, which also includes everything is about 50GB in size.
Kraken texture compression might be a bit better, but it is not that much better. At best maybe 10% on large data. This can be much, but it is not 50%.
And before you begin with oddle textures, that works in all current-/last-gen systems.
