I don't really understand what you're saying... because apart from in rare cases (test discs with tracks without RIAA), it seems to me there is no reason to remove the RIAA...in fr , thd , imd, crosstalk....w&f...

perhaps in your various tests you have come across the fact that it is probably comfortable that "the correction remains in place" whatever the manipulations differents types of mesureaments ... as long as we do not decide to explicitly remove it .... (?)

your software deserves a "riaa correction" hdg

i try it and seem ok now...! top....

(here just to validate observe the behavior of a means of acquisition of fr above" 1-2k to 20k,or more", to observe the behavior and help to adjust somes parameters (capacitance etc) of mm cartridge etc, seems quite sufficient and rigorous for my use ;-) )

My point and my observation is just that it seems that there is an little approximation in your 2 riaa files..4k/10k

observe my level of precision of level
(observations rather around 0.05 0.1db etc.)

here I was using sweeps taking tens of minutes in virtins... (the more classic "white" approach that I point out with mt takes much much less time and the riaa "without doubt").... if necessary in virtins I will just use the "playback" file (python is extremely powerful and precise but I do not have ...

it seems to me that it is not the method but your cal file which has this particularity...
