Much of the data saved with the file are algorithms that are patented by Canon. However, the software can only apply generic settings. If you use third party software, there is an option to process the RAW file using the camera settings. These settings are then applied automatically when the RAW conversion is done, but only if using DPP. The camera saves the RAW image file without applying any corrections, but instead saves the settings you have chosen as data within the image file.
If you shoot RAW the process is different.
