I intersect the line of constant L and H with a polyhedral approximation of the Rec2020 gamut. This was supposed to be the first step towards getting within the neighborhood of convergence for Newton or Halley iteration, but the results were okay and I was running out of time.

It has lots of drawbacks (like slicing off a large portion of the gamut), so it's meant as a stand-in for something "like that but defensible".
