As an experiment, I also generated spokes of 31 hues evenly spaced in Oklab h, with varying L and C to make a cylinder of evenly spaced values. I then converted those to XYZ and then to ACES. I eliminated any values that fell outside of Rec709 primaries and I ran those values through A, B, and C and looked at the chromaticities before and after the rendering.
And in Oklab:
In terms of input and visualization space, what other ways might it be useful to compare the renderings?
