You can use a workaround with OBS Studio. Use the webcam as input, apply 
the "Color Correction" filter to it, and use "Virtual Camera" as output. 
OBS Studio can run in the background, while in Zoom you can select the 
virtual camera as input device.

As far as I know, with FFmpeg a "virtual camera" output is possible 
under Linux but not under Windows.
