FAR easier, faster, and cheaper to have a 0% and 2% PLUGE pattern or digital 16, 17, 18, 19, etc. pattern (having below black would be helpful but not completely necessary).
The are called light meters because they are good at measuring light and not good at measuring dark.
I think something like a C6 would fare quite well, especially if the display in question only had an average or poor black level. Have you had the opportunity to test out a meter from D3 family (C6, D3 PRO, OEM i1Display, etc.)?
CNET uses the following metric for MLL:
Good: +/- less than 0.009
Average: +/- 0.009 to 0.019
Poor: +/- 0.02 or higher
