I posted a comment about the numbers not matching up on the chart and why that is somewhere else, so here we go:
Numbers that don't match in the chart. This is the harder one. For example, if we are looking at the Red chart for RGB, while the Red value is what we are focused on, there are still G and B components to that, we are just less concerned with them. However, you can have a value where you are looking for Red 0 and get Red 0, but Green should be 15 and you get 14, or Blue should be 8 and you get 9. In this case the Red value is correct, which is our primary focus, but something else is a little off so you can get the reference value, but still have a very small dE 1994 introduced.
I'm also working on a better way to present some of this data in the future. As each colorspace we test produces 768 data points, and some players can offer 8 sets of data (2 HDMI outputs, 3 colorspaces and Source Direct) to test, I'm writing some software to better present all the data than trying to manipulate it in Excel.
