Interesting article. It doesn't explain why I sometimes get a pic that has a good histogram in RAW, yet it becomes oversaturated when converted to TIFF (or other file type). This occurs for either sRGB or AdobeRGB. I have to reduce the exposure then it is ok. This happens with Sony and Canon RAW files. It's not common, but common enough to be annoying.
Just as a note, I do tend to process in AdobeRGB as I do have a wide gamut screen and it does make a difference to what I see, if not what others see. I agree that it makes zero sense to process in AdobeRGB if you can't see the result.
