Fringe Saturation in Post Process Volume not functioning

Setting the values for Fringe Saturation within the Post Process Volume does not seem to have any visual change.

The documentation suggests that changing the Fringe Saturation will either increase or decrease the sharpness between a 0 to 1 value.

"A scaling factor that controls the saturation of the shifted colors. Lower values produce a more blurred result, while higher values make the color shifting much more pronounced."

1. Open a default template project with a Post Process Volume.
2. In the Post Process Volume expand the 'Scene Color' dropdown
3. Set the 'Fringe Intensity' to 5.0.
4. Now set the 'Fringe Saturation' to 1.0.
5. Alternate between values 0 and 1.

Outcome: No visual change when setting the Fringe Saturation.

Expected: The blending of the fringe colors are either sharpened or blurred.
