While avoiding saying outright that this is the case here ... *If* it is 
a way of fingerprinting or identifying, when used with a combination of 
other accessibility related changes in the browser,
that the person may have a disability. Then I would say yes.

Many will use dark mode, just because they like it and not have any 
accessibility need, and they may not stick out from the herd etc but 
this information when used in conjunction with other unique 
configuration settings such as a larger font site, particular font 
usage/symbol sets etc may be used to identify users with disabilities.

My 2 cents, thanks.
