The measures screen also has a "Selected color" area that also displays R, G, and B numbers. There are also the "Target" bars that show how red, green, and blue relate to each other as a percentage (%), but I suggest looking at the R, G, and B numbers that generally are comparable to Y.
If you measure grayscale you would want the R, G, and B numbers to be approximately equal. As you turn up the contrast control you may find that one of the colors might stop increasing along with the other primaries. For example say a TV runs out of red, so R will get to a point where the R number might go no higher, but the B and G numbers can get much higher. Since R is unable to get any brighter, it would be necessary to set G and B to that same maximum value in order to display gray.
I've missed your reply. Thanks for the help;)
