I can't say exactly how your car is working, but in the E9x models the driver's side could have cooler air from the centre air vents by design in similar settings. To do with comfort for the passenger, when the driver controls and runs extreme settings.

What happens when you turn it up or down, does the blending change as you'd expect?

Another factor is timing from changing the settings and cabin temperature. Some reactions can be in conflict at the extreme settings. 16.5C may be completely different, as it is a regulated temperature. 16C is also referenced as 'LOW'.
