I once looked over the shoulder of the service receptionist when I booked my XC60 in a few years back - there's a system which appears to list everything that has been done or ordered for the car through Volvo or their official network - for example it listed the build date, options, the fact that one of the options was a tow bar but that was dealer fit etc. and all warranty work.

Hence I would be surprised if the Polestar software upgrade is not recorded.
