Proof is relatively easy for BMW. Telematics nails the obd2 connections in real time. Hysteresis adds another nail plus nails the non obd2 like RaceChip that I use.
I use it knowingly, if I break it, I buy it. Local dealer generally will not be an issue. If NA gets involved, they will know.
Just had a service. Left the RC installed out in the open. They flashed the DME, oil, etc. Zero issues.
