Linux/Wayland,
It gets told through portal. Before 6.8 portal wasn't inherited at all and was always returning Dark based on theme name (even though it's not really dark unless I enable dark theme switch as you could see). It seems it's because Qt asks portal but doesn't synchronize gtk state to the value. This should make it to still inherit portal by force applying dark colors to gtk theme when portal says so but always return the value based on actual colors so colorScheme is always synchronized to the visual state (what should also fix QTBUG-123031):
