I think I can discern what a number of these would be:
First few seem to be screen area settings, obviously.
The next few seem like they might be:
GDRV - Green Drive
BDRV - Blue Drive
GCUT - Green Cut
BCUT - Blue Cut
These seem like they would be your gain (drive) and offset (cut) values for setting the white-point, with red being used as a reference, I guess. I'm not sure these would really help you, unless green or blue were saturating before something else.
After that, it looks like there's Contrast, Hue, Color, Brightness, and Sharpness, which you have in the user menus anyway.
These three are kind of curious: RON, GON, BON. Seems like you should be able to set RON, and GON to 0, and get a blue only, picture. I always like to set color and hue that way, with test patterns that have overlapping areas of blue, cyan, and magenta. You could achieve the same thing with a blue filter sheet, though.
I don't really see much else aside from gamma (GMMA), which I personally don't even really like the concept of, since it's a not linear function. Also, there appear to be balance, bass, and treble settings for the sound, but that's not really relevant.
Maybe some of those other settings in between do something magical, but in terms of DKC, I found that game to be pretty dark when I was playing it. The stop-go level was basically pitch black when the lights were off, for instance. Do those settings in DKC give you a better color gradient in the test suite? Might be too much to expect perfect results with composite video, though.
