On my Mi 9T, the fix disables "Global Dark Mode" feature (and fix the status bar color), so the new "Individual app" feature is not used.
And you must NOT go in "Dark Mode" settings menu if you want to keep the fix or you will need to apply it again.
EDIT: I don't know if scheduling "Dark Mode" before applying fix will keep it...
