I'm not sure which Koen used. Also just to be clear, none of this involves PCA, my earlier PCA was on the MSI images.
This just requires sampling and reading the white and yellow levels at different points. I independently checked them against the MSI and it is extremely close. Quimqu checked and found the pages show the same contrast in the same image -- so I think Koen's results here are valid, but I agree it would be nice to double check on the other image sources, and ideally to compare them against the MSI as well to get an idea of how biased they are.
