I guess that - after correcting my idea how it actually works with your input - the above is now my question (reworded, but basically the same: will LSD be used efficiently in DSC ON driving scenario)?
TIA!

There are different types of LSDs. The viscous units (like the ones used in the BMW E30 325iX) are activated by wheelspin. The more difference in wheel speed, the more it locks up. The fake e-diff is also in this category. You can feel it lagging a bit when driving on the limit.
The clutch pack units (BMW Performance LSD) and TorSen (Quaife) are activated by torque differences, and will usually react sooner than the car electronics. This way you can drive with a heavier right foot before the DSC warning lamp starts blinking.
