A good eye, and you can look at a 5% pattern and see the greenish tint to what should be a dark grey. The other issue is, if you go into 2pt low and click blue +3 or 4, it is going to increase 10 to about 50 more blue. Blue is a much better color than red or green to have too much of, and green is the worst offender to our eyes.
The other option would be to use 20pt and 5%, and add some blu there. I think people have seen some green from 1-4% as well, and just adjusting 5 would not address most likely, but I have not messed with that.
I just did as Chad suggested, I used 2pt low to fix 5% to a low error which makes broad changes of more blue to the whole low range, and 2pt hi to fix 100%. I never touched those controls again, and use 10-95% 20pt controls for grayscale and gamma.
If you have some cash laying around, you could grab an i1 display III OEM (EODIS3 is $249 on Amazon for example) for cheap and use HFCR that many have talked about here. These cheap colorimeters are not good without a profile for color work, but are pretty easy with grayscale and good enough for our work. be careful if you go that route though, it will suck you in...
You can get HCFR for free, but
has done a lot of work so a donation would be nice
