Key color spill reduction does nothing

I have a green screen setup that is not professional but is OK. The Chroma Key filter works quite well, except that there is too much spill, i.e., a green fringe around the outline of the person. The setting to help with this would seem to be Key Color Spill Reduction, but when I increase its value, all it does is desaturate the keyed image. It does not reduce the spill at all.

I've done a little chroma key work in video editors like Premiere Pro and the spill suppression there can be quite effective.

Am I missing something for how to use this properly in OBS? Any tips would be appreciated.

Hmm... the internet is telling me that 3 feet is not enough. Let me try to create more distance.

Update: Was able to make it 4 feet. That helped. Still wish the spill reduction did something though.
