Comment on graphics contrast 680

Hi everyone,

I could do with some help for this comment:
https://github.com/w3c/wcag21/issues/680 

The cross-tester aspect I can deal with, but for this bit:
" we believe it is reasonable to assume that users in need of higher contrast in graphics would also need the same higher contrast when they are not using the web. It stands to reason that high contrast theme or similar OS accessibility features should already be in use. With high-contrast (or equivalent) turned on, the test result would likely be different."

My question is: How well do higher-contrast OS settings help with online graphics?

I had assumed that the contrast was relative, and turning it up at the OS level wouldn't really help with things like charts or icons on websites.

Does anyone have personal experience with this, or know whether it logically stacks up?

Thanks,

-Alastair
