What you are looking for is when color is not being added anymore. You will most likely run out of red first. My red output peaked at a setting of 89/100. One step higher and red output dropped 3%. That is now the max your contrast can be without discoloration.
Out of curiosity, which ChromPure module were you using to measure color output?
For a back-light check, go to the APL clipping pattern and make sure you can see 19-21 & up flash. If you can see below that, chances are your back-light may be too high.
You're clipping 17 & 18. Black level is incorrect at this point.
