> The “raw” data in so-called “raw” image formats in not unprocessed data from the image sensor.

RAW images are completely un-demosaiced and otherwise unprocessed sensor data, dead or stuck pixels and all. It's the job of the RAW converter (whether performed in-camera or post-capture) to hide those in the conversion to a standard color space.

Manufacturers are now blurring the meaning of RAW to be closer to what you imagine. For example, Apple's ProRAW images are demosaiced and heavily processed.
