Saturation

Saturation describes how intense a color looks relative to a neutral gray appearance. Reducing it moves colors toward gray. Increasing it emphasizes their color. This differs from brightness, which concerns lightness or output. It also differs from hue, which describes the kind of color. EIZO's color-control reference

BetterDisplay can provide saturation through hardware controllers, software Image Adjustments and Video Filters. Choose the path according to what you want to affect: a monitor setting, the display's software-adjusted output or a filtered stream.

The numeric scales are not interchangeable. A stream filter's neutral saturation is 1.00, for example, rather than a percentage measurement of the physical monitor. Having a software effect also does not mean that DDC can provide an equivalent hardware control.
