This page was interresting and demonstrates some problems with CIELabls hue perception: https://raphlinus.github.io/color/2021/01/18/oklab-critique....

Oklab is mentioned in the article as also being flawed in this sense.

A significant mis-step - naively eschewed actual lightness, the thing that dictates what people actually perceive, because people outside the field regularly conflate brightness and lightness.
