I think this shows a true feileadh mor. Your confusion is, allowing for artistic licence, due to what appears to be a large plaid setting. Bear in mind that the plaid section is a right angles to the kilted section.



I've circled the features that appear to be the same part of the sett (note how even these have slight 'artistic' differences) and then placed a straight line in the apron and the corresponding section of the plaid which I believe to be the same. You'll see that it's possible to account for the differences you speculate.

I doubt that fading would remove completely the broad darker sections circled.

What's also interesting is why the doublet is painted unfastened in the middle. Perhaps that was a gentrified/courtly fashion at the time.
