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

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.

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

I was looking out for a mention of Oklab and didn't see it while reading. If anyone else is wondering, you have to click on the [1] footnote to see it.
