I recently tried to switch Windows 11 to high contrast mode at work to back-date the flat design and make it easier to use, but it broke around 50% of the apps including Gmail on Chrome (got solid black letterboxes). A few things worked out of the box like Office 365. Anyway, high contrast mode looks OK on Windows 11 but the apps integration is a sad state of affairs right now.
