Bruno Chareyre proposed the following answer:

different response depending on the input capillary pressure

In the pendular regime, no. It will never be very different. It is a
physical feature also observed in experiments (as long as the
experiments are in pendular state).

Beyond the pendular state the effect of capillary pressure is more evident, but you need a completely different model.
One possible option is the 2PFV method, which now has an example script here:
