RAW is compete sensors read-out, it handles 16-bit, but is limited by dynamic range of digital sensors, so it's colour capturing capabilities range from 12 to 14 bits.

You are saying that digital camera, when saving to JPEG, after performing gamma compression from the 16-bit raw, just truncate the result and not doing some kind of dithering? While I don't have resource on hand to confirm or deny that, I find it unlikely that don't at least do ordered dithering.

I am not sure if Kindle even do any dithering outside of cover images. My experience with Kindle is that it posterized all over. Hence needing dithering beforehand.
