I don't know about the GM sensors but I suspect that all OEMs go for the cheapest sensor they can procure. That would mean sensors that are preconfigured to the vehicle or set of vehicles they are going to be used on. That way there is no need to program at the assembly plant or in the field which avoids labor charges and could reduce equipment costs. At the plant, they might check the sensor's battery and broadcast capability and then slap the sensor on the wheel and slap a tire on the wheel or they forego the sensor check if the sensors come from their factory with few battery or broadcast issues.
One thing I do know is GM vehicle lines can use different sensors than other lines. For instance, I know the sensors used with our 2015 GMC Terrain are substantially different than the sensors in the 2015 Corvette. That may be because the Corvette sensors broadcast tire temps in addition to pressure readings to the car's systems. With the Terrain, the sensor valve stem can be replaced without replacing the sensor. With the Corvette the complete assembly is replaced.

Thanks -- I am coming around to the (unproven) realization that the OEMs probably use preprogrammed, non-reprogrammable ("OTP") TPMS sensors, and especially if they did the vehicle's TPMS system right, these are automagically accepted into the vehicle's TPMS system after a few miles of driving. Hence never a need to change whatever IDs come with the sensor from the factory. This would explain why most programmers don't even offer OEM sensor (re-)programming, just aftermarket sensors. This also explains the lower price for OEM sensors than for universal / aftermarket sensors.
I got a Schrader EZ ("universal") sensor to play with, and it's certainly easy to (re-)program for the Corvette. I should try it for a totally different vehicle (like, Japanese) to confirm.

I got my 19 in Dec of 19. Feb2020 I ordered wheels and tires from Tire Rack and of course had them install sensors also. I installed the new tires/wheels and immediately went for a 20 minute drive. As I was turning the car off in the garage I realized I had seen nothing abnormal the whole drive. Since then about 2/month I swap tires wheels to run autocrosses and I have never had a tpms light problem w/ either set.
