Are you referring to the register values tagged as WhiteLevel in my dropbox graphs, or to values detected by raw_diag?
In any case, feel free to use them for RawTherapee. I took the AMaZE algorithm from them, and I'm thinking to send them a patch for floating-point DNG support (my version doesn't open CeroNoice DNGs, but didn't check the bleeding edge).
If you collect a table with white level values in a nice format, I'd be interested too (just to have them organized).
I think raw_diag white levels is what I need .. basically the values that are same as if I would inspect the raw histogram for white clipping. This for normal Canon cr2s not ML modified .. and I think ML should also target to the same WLevels as the native Canon cr2s.
I would strongly prefer to use the exif data (specularWL) so the best would be a DCraw patched to use the tags, but I have to recheck as I remember a not insignificant deviation from the histogram derived WL in some rare cases ..
floatDNG is not supported ... waiting for your patch ..

The WL info will be freely available in RT code just search for the "camconst.json" file. I don't know if you'll like the format but as I will use spreadsheet to get the data ready I can sent it when it's ready ..
