If you have a game, where you have large packs of files (like a 2GB sized textures.pak), and in a patch you want to add 2 small things, you can just ship the differencd between the old anc new pack file, and skip transferring the rest.

They do this, but not as a binary diff. The new files are just shipped as an override of the old files that are loaded after the old files. It's substainally faster than applying a binary diff and file sizes really aren't a concern for the most part.
The game industry really hasn't used binary diffs and patching since the 90s when they used RTPatch.
