Interesting, I've never seen that definition before. Personally, I think it's best to use either sRGB/P3 white (which makes sense for CSS Color 4) or ASTM D65 (seemingly used to derive some modern color appearance models; at least, this is what I observed for ZCAM/Jzazbz) in this case, but I don't think it matters much as long as it's internally consistent.

The reference code for CSS Color 4 is currently using sRGB/P3 white consistently, so nothing is actually wrong with it. It's just odd that matrixmaker.html was changed later and no longer agrees with the sample code or GitHub issues.
