Rimmer -
This is OT, but in an earlier post you wrote something that indicates a misunderstanding. You wrote, "So, here are a couple of 100% crops from the Quick Check Tool in DPP, the first being an unadjusted RAW file,..." First, Quick Check always shows the jpg made and embedded in the RAW file by the camera. That's why it's "quick." Any other display (Edit page or Edit Image page) has to do an on-the-fly conversion from the RAW data to an RGB image according to the tool palette configuration, which takes several seconds. And second, because of this there is no such thing as an image from "an unadjusted RAW file"; it is always either default-adjusted or user-adjusted.
I know it is difficult to remember that although we talk about seeing the RAW we never actually do. We see a provisional conversion.
