Does the temperature gauge display water temp or oil temp?

In my previous F30, the temperature gauge on the dash was definitely oil temperature - it took quite awhile to get to operating temperature especially on a cold day. The car would even be blowing hot air for awhile and yet the temp gauge was still showing cold.

Now however on the G20, I notice the temperature gauge gets up to temp really fast - like within 2-3 minutes. Granted it is not winter out yet here in Virginia, most mornings are in the 50's (F). I can also get in the car 4 hours after driving it, and the temperature gauge goes to operating temperature almost immediately.

I couldn't figure out if its reading the water temperature or if this is from the new active grille that stays closed to warm up the car faster.

If it is reading water temperature - I wonder is it possible to code it to read oil temperature instead? Since it is a digital dash board, I figure it might be possible to change this.
