I think it will be useful feature to save "Fine-Tuning Analyser" graphs separate from "Device Noise Profile". It gives an ability to get noise structure maps from black shot (without the lens - closed body) and apply to it saved lightness "Fine-Tuning Analyser" graphs. I means that we get noise structure from one file and the noise amplification by the lightness from another file.
It can be useful when i make grey shot with ExpoDisc (or black shot without lens) in real condition for noise structure but already have noise amplification map stored file.
