Yes, only in the Pro version though.

64 levels is plenty, I guess.

I have to try this. So far, the software is reporting ridiculous Delta E
values like so:
# R G B DE
1 255 255 255 0.12
2 191 191 191 1.21
3 127 127 127 0.87
4 64 64 64 1.29
5 255 255 255 0.32
6 255 255 127 61.27
7 255 255 0 89.59
8 255 127 255 77.48
9 255 127 127 72.28
10 255 127 0 97.23
11 255 0 255 106.05
12 255 0 127 95.63
13 255 0 0 0.42
14 0 255 0 0.24
15 0 0 255 0.34
Average delta E = 40.29
Maximum delta E = 106.05
Thank's for your help. I'll continue my investigation...
