Yes, I have the same offset. My 2019 5 series had the same issue. Interestingly my wife’s Acura RDX is dead nuts on.
I have been too lazy to check but does the off speed translate to a corresponding error in distance travelled also? If you travelled 1 hour at 80 mph would you have only gone 77 miles?

On the 992, it’s always less. Car showing 80, but gps showing 78. My buddy’s 992 turbo is dead on accurate 🤷🏿.

So, doesn’t that effectively reduce the warranty period by the error rate in the mileage? Not huge, but over a large amount of vehicles, it could be a significant savings for Porsche.
