I think that trying to extract meaningful results for the relative distortion caused by stranded versus solid core speaker wires by means of acoustic measurements in the listening room is a process fraught with too many measurement uncertainties. Any effect, if there at all, is going to be tiny, and is liable to be "lost in the noise" (literally!).
As a start, it would be good to compare several of your distortion vs frequency plots for the *same* wire configuration, to get some feel for how much variation there is between one run of the distortion measurements and the next one.
But in any case, if the object of the exercise is to measure the distortion caused by a length of stranded wire and compare with a length of solid core wire, then the precision and reliability of the experiment would be greatly increased if the measurements were made purely on the electrical signals in the two cases.
