If you are worried about leaks, one quick check is to pull up the carpet and the piece of wood below the carpet in the rear trunk and look for fluid. If you find some, the expansion tank has a leak. If you find fluid on the ground under your car, then you know it's a hose.

I do believe the system, even though it's a closed system, does evaporate a little. Also, very cold weather is going to reduce the volume of the coolant compared to temperate or hot weather... but not by much... probably what you're seeing.
