A lot of that is shadows and lighting data, sometimes in unusual data structures without readily available compression methods. Compressing textures also impacts load times, obviously decompressing 10gb of jpgs could take a while. Still probably there are good compression methods and good tradeoffs to make, if any AAA studios actually cared about storage space (They do care a lot about GPU memory, just not storage space).
I wish games would release with low/medium, up to 1024x1024 textures and stuff by default and let people choose to download/install higher res stuff. If I’m not going to use the 4k pack, I don’t need it sitting on my hard drive
