That was true on the original D1 but I thought that it changed on the later versions but I'm no expert on either account. I remember when the D1 came out being surprised to learn that raw wasn't really quite raw in the way that I'd known from use of various Kodaks. I think the camera did some sort of analog sensitivity adjustment based on your white balance (and ISO) setting. You could alter white balance in raw processing but not with quite the same results as actually setting it in camera before exposure. For example, gain on the red receptors might be turned up based on a white balance setting that needs a higher amount of red. I seem to remember the third party NEF processing developers (Bibble, Qimage) describing this on Juergen's D1scussion list during the early efforts to figure out how to decode NEFs. That was a few years ago. I've slept since then... memory's a bit hazy.
