In brief - no Mark didn't.
But I referenced a similar test I did conduct in my "Printing Can be Fun and Easy" Article, different printer and paper. It requires making the prints, then scanning them such that what you would see on your display kind of mimics what I see on paper. Extra time involved, and I decided that such a demo wasn't really necessary to the key points I was looking for and wanted to convey in this article. Not to say it wouldn't be useful as a check on the difference between observed colour appearance and statistical outcomes. Who knows - one of these days I may just crank it out, but it's been busy times lately.
