In this case of programmed universal TPMS sensors with the same tires, you don't have do anything for the tire type in the vehicle settings - it should just work.

I have the BMW winter wheel package which comes with OE/vehicle specific sensors. These have their own IDs as they were not cloned from TPMS sensors already on the car. When I switch between the summer and winter wheels, I do change the tire type in the vehicle menu to indicate the car should start identifying new TPMS sensors. On the car, there should be three sensors/receivers so they can be used to triangulate the position for each of the TPMS sensors (FL, FR, RL, RR).

In this case of vehicle specific TPMS sensors broadcasting their own unique IDs, the car should detect a loss of all four TPMS sensors and show an error. I would not expect it to automatically pick up the new sensors. It would also require a change of tire type (and potentially change back to original) to reset the TPMS learned IDs.

I will be switching back to my summer wheels in the next month or so but this time, I'll go for a drive without resetting the TPMS (by changing the tire type in vehicle settings) to see what happens and if DSC becomes more restrictive when the error message is displayed.

That definitely makes sense. I can see why my installer cloned mine versus a summer/winter set. You would want the car to detect a new set when you change from summer to winter and vice versa so that it throws the error and forces you to take action. Whereas with me, I just want it to work and I don't need to take action.
