I understand that scanning can change the properties of negative film. However, are these changes consistent with what I am showing in the images above? Would so much color be added to a low saturation negative? The amount of color I'm seeing in my images is really much higher than I was expecting.

If you underexpose film, colors are said to be more saturated. Since you have highlights in your scene, depending on your metering method chances are high that you underexposed these shots.
