I was given this in vector pdf format. When I create 3 squares each with the different formulas they all look different. Which do you trust to be the most true?
Ok, the question is this, are any of the swatch colors based on a conversion from one of the colors?
I.E. is the 143 C created by converting the CMYK and is the RGB created by converting the CMYK?
I would suggest that the 143 C on the to row was getting its RGB numbers from the same RGB icc profile as the one on the bottom row but a different CMYK profile.
