I have a bunch of stuff in the barn that I bought last year on cutout, and I don't even remember what the brands are. They tend to be standard mini incandescents, so one of the supplied curves will probably work for those.
I'm currently working on a (very) small Halloween display for a trunk-or-treat event. I'm thinking single C7 bulbs per channel in pumpkins. I'm seeing that the different colors of the same brand bulb have significantly different characteristics. For example, blue turns on at about 15 and maxes at 255, red turns on at 3 and hits the blue max at 176. I would like to do a dumb linear curve between the observed unnormalized min and max points.
If the format is proprietary, I guess I can't do that.
