Video tools for darker skin tones

The video processing tools feel biased against those with darker skin tones. Zoom is an integral part of work and how we do business. Careers depend how one shows up on Zoom in meeting and interviews. Sadly, Zoom does not seem to be able to handle lighting adjustments for people with darker skin tones.  The person is either too dark or over exposed.  As a result, darker skinned folks tend to have their cameras off more often which creates disengagement.  This has a tremendous impact on work and society.  It means that people with darker skin tones have to work harder at work to look good on Zoom.  It means that diversity takes a back seat in the workplace.  With all of the available video processing tools, this should not be an issue at all.  This feels like a testing bias that could easily be remedied once you are aware of the challenge.
