I've seen that, but:
For certain RAW images, the shooting conditions may be applied when developing the images. (Images taken using the Black and White and Cool settings are developed in black and white or cool.)
Basically, whatever gets presented on screen - via any application -- is an interpolation. Screens can (at best) display 24-bit rgb.
BSI-CMOS sensors capture 12bpp or 14bpp, thus you need 48-bit rgb to store all the info.
