Luminance is more pronounced than chromaticity when perceived by the eyes. Therefore, many of image compression techniques reduce the number of bits used to represent chromaticity without affecting the final visual appearance too much.

The chromaticity formulas remind me of the formulas for the barycentric coordinates for a triangle. I wonder if this just a coincidence or if there is a deeper underlying connection.

To add on to the above, it's important that the chromaticity region is convex, or else these types of barycentric calculations wouldn't give us sensical answers all the time for any x+y+z=1.

What is the main difference between luminance and chromaticity? I'm having trouble distinguishing between the two.

From what I understand, the chromaticity relates to the hue and satuation of the color. In other words, the color's wave length and how close is the color to the center. The luminance can be thought of as the brightness, which is not shown in this 2D graph. 0% luminance is black and 100% is white.
