Those codes are just units of color correction applied. They probably would not tell you a thing that would be useful at all.
I do know that on a Fiji 390, the code "N,N,N,N" means all internal corrections have been turned off. When I was using color profiled Fuji Frontier processing, I always made sure to request "Turn Off ALL Automatic Corrections", else the unskilled operators always tuned on the "Bozo The Clown" correction set used for the great unwashed and their weekend snapshots. The one that makes everyone look like they are dressed in circus garb and gives all fair skinned people a 'Fuji Sunburn'.
Go here if you want to bother with profiling your local Frontier.

I gave up because the pre-pubescent, nose-picking young idiots hired by all the local labs never bothered to take their fingers out and turn off the damn corrections the first time no matter WHAT instructions I left. I ALWAYS had to have everything re-printed. Then I found a new pro lab (my old one went out of business
🙁 ) and have not bothered with Frontier labs again.

PS: It is not the machine at fault. A correctly profiled Frontier using Fuji Pro paper is capable of wonderful output. The crap Fuji Crystal Archive paper that all the Big Box and One Hour Photo stores use is, IMHO, not worth bothering with.
