Lumetri saturation control jumps in 32bit linear compositions

The saturation control in Lumetri is not smooth when working in 32bit linear projects.  

The default saturation value in lumetri is 100, changing this to 101 results in a noticable jump in the image.  By comparison, changing saturation with the Hue/Saturation effect results in a smooth change.


Steps to reproduce:

1) Set your composition to 32bit, linear

2) Apply the lumetri effect to some footage

3) change the saturation between 100 and 101.  There is a big visible jump.

4) Turn linear compositing off

5) The change from 100 to 101 is now smooth and invisible/


** I have reported this bug before a few years ago. I thought it had been fixed but I am noticing the same problem again in AE 2023. Maybe it wasn't fixed, or maybe the same bug has come back? **
