bar comparison?

this may not be possible, but I think it'd be cool if qct-parse (or signalserver) could perform a color bar comparison, not just detection and disregard. I'm not sure exactly how detection is currently implemented (looks like it's based solely on Y values), and I'm sure if/how chroma-related signalstats values (U,V, Hue, Sat) translate to specific vectors, but I always perform a quick color bar check on any file that has bars at the head (if the bars are way off, I'll review technician notes for a justification). Finding a way to automate this process, and flag the worst offenders, would be really awesome.
