Your OKlab vs HSV plot is useful, but left me curious what that would look like in CIE Lch just varying hue. It seems the most direct comparison to me, just workign in LCH vs your proposal and the post isn't super clear about the benefit.

There are a two different CIE LCh color spaces: they are cylindrical samplings of CIELAB and CIELUV, similar to how Oklab can also be sampled with cylindrical coordinates

The comparisons with CIELAB and CIELUV are using LCh coordinates. That’s how hue and chroma predictions are made using those spaces.

Actually, I'd love to see this sort of hue-only varying comparison to several other popular color spaces, including CIELAB and HLS, too.
