CT Raw images are heavily delta compressed with a specific algorithm that was designed to work with bitcell data (only!); that's why it takes some time to produce output in that format.
The encoding works in a way that allows standard dictionary based or statistical compression to still make the image smaller later on, which wouldn't work very well with the original data, which is usually about 12-16MB in its original state.
