Default 2015 K9, AC curiosity when sunshade is open

I recently purchased a 2015 K900 Luxury. It's still under warranty so I want to fix everything I can while I can. I noticed a weird abnormality with the AC that makes me go DUH.
It's common on luxury vehicles to reduce the AC air flow through the vents when you are on a bluetooth call. This makes lots of sense to reduce background noice of the fan blowing through the vents while you are holding that important business conversation. What I've seen and can prove is that the AC cools less when the sunroof's sun shade is open. I can not understand this logic. Open the sun sunshade while keeping the sunroof closed and the AC blows cool. Close the sunshade and the AC blows COLD. It's not the speed of the fan, its the cooling temperature of the AC. I'm a tech geek so testing this premise and validating it has me thinking , I must be crazy. There is no logical reason that I can think of for a system to perform in this manner. Can anyone else verify or validate this happening?

That's interesting! I don't think I've noticed this. I'll check and see.

For a day it consistently cooled the cabin in the manner described, if the shade was open, then it would restrict air flow and the air temperature would not be very cold. Now it is working but still not in a manner that I would deem consistent or correct.
I'll just ask the KIA tech about it next time I drop by the dealer. I know the degree to which vehicles are controlled by computers.
This is really weird, even trying to describe the behavior is challenging.

I did try to detect this on my car, but I just couldn't. A/C seems the same regardless of shade status.

It's a real curiosity. Let us know what you find out.
