There are RGB High and RGB Low controls as the grayscale goes from 0-100IRE (Stimuli). The High controls have more impact on 50-100IRE while RGB Low controls have more impact on 0-50IRE. On most displays, including the Kuros, you need both sets of controls to correct grayscale errors.
I am confused that so many are posting that the Low controls actually do anything. I have two 6010s and calibrated both this weekend and with a DTP-94 meter and when putting up a fixed 20 and 30 IRE pattern, adjusting any of the LOW controls had no effect while in the service menu. Adjusting the Highs showed immediate effect all across the intensity axis.
The 5010 service manual states that the default values for Lows are 512 and fixed. Unless you have to leave the service menu to test the low changes, I don't see on the non-elites that the low controls are active (and I really, really need them! I can't get Blue to track red and green below 30 IRE.)
