As shown in the 16/11/2022 meeting plotting constant hue lines near neutral has a slight hook/kink. May be related to #3

This may be a clipping that happens when in SDR it hits display white (128 in linear). This wasn't visible with the older tonescale since it hit display white at max ACES. I only see this in Hellwig. I assume this is when the M component collapses to 0. Following is ramp with ACES whitepoint shifted to DCI whitepoint and given as input to the DRT (v24).
