I'll take a stab (not saying this is totally correct, just my thoughts :) -
The arc of forgiving vs. ruthless is talking about resolving power, which would fall under the domain of precision. If you have a crappy recording then artifacts will be exposed in a non-pleasant manner. If you have a good recording then more details will be unveiled.
The idea of something being colored vs. giving a truly balanced representation of the audio spectrum would be under the domain of accuracy. For instance, if certain frequencies are more recessed or more forward than intended by the recording engineer.
