But VSCode specifically queries for "max", and so it only turns on that mode for people who prefer max.

I seems like the main disagreement is with the vocabulary. We're using the term "high" differently. 

To me, "high" contrast means ~"max or nearly max contrast"… iOS and macOS do not have a system setting for that (it's "increased" a.k.a. "higher, but not high"), but both those platforms _could_ have a true "high" or "max" setting, so I'm hoping we can avoid using the term "high." 

I wouldn't have thought "high" contrast would be a subjective term, but as it's clear several of us are interpreting it differently, it's likely that authors will too.
