I'm not sure I would completely agree with that. DSC doesn't directly know that you may have different grip levels at those axles, but it is able to infer it based on how the car is handling and of course the sensor inputs (like the wheel speed sensors).

If anything, I would hypothesize that the DSC programming is optimized to assume you have the same tire on all four wheels. If you are getting a lot of understeer because the front tire compound isn't as sticky, it will be cutting the throttle or brushing the brakes to try and tuck the nose into a corner.

You could test this theory pretty easily by running a different front tire one session and then swapping back to a matched set the next one and looking at the telemetry.
