Image Quality Differences Between Races

In reviewing some recent video of a subject who committed a vandalism, I notice the normally good image of the person coming in the door from outside was poor with the African American subjects. The WDR of the Dahua camera couldn't compensate for dark skin color.

So I started looking at a number of camera comparisons on IPVM and found that almost all camera tests are conducted with Caucasion male subjects.
