Unfortunately, 2351, I don't think you understand there is no such thing as a raw histogram.
The RAW file contains only monochromatic data for starters. That's why I was asking you about this D810 upgrade you were telling us about. You still haven't replied.
You always need to render a RAW file to see a histogram or preview image or live view or whatever. You're demosaicing, applying a tone curve, white balance, etc. An inherent problem with JPEG is that you're crushing all that data down to 8 bits. But I don't know of a camera that displays TIF, for instance.
You might Google 'RAW conversion' or similar to learn about the process.
