Surely this would be even faster and potentially better with OKLab? Especially in the context of CIELab based distance metrics like CIEDE2000 which are a bit heavy.
My own gripe with box cutting is that perceptual color spaces tend not to have cube shaped volumes. But they are very fast algorithms.
