There is no “high contrast”. Increase Contrast has roughly the same (limited) effects it always had (enhancing the presentation of specific UI controls in specific ways), hence it’s not broken. What I’m saying is that Reduce Transparency is reducing contrast in a way that is orthogonal to, and isn’t prevented by, also having Increase Contrast turned on.

Features like Night Shift also happen to reduce contrast. That doesn’t mean they are buggy, or that Increase Contrast is buggy.

It does mean that Reduce Transparency is not suitable if you don’t want reductions in contrast compared to regular-transparency Liquid Glass, regardless of whether you also use Increase Contrast.

I do agree that Liquid Glass as a whole is broken for anyone needing a higher-contrast UI. In my opinion, a GUI should be reasonably high-contrast by default, without special accessibility settings.
