Bruno Chareyre proposed the following answer:
> the capillary forces remain constant. So if i compare two scenarios
having different capillary pressure, then my void ratio-log p (where p
is the mean contact stress) relation is same

This is not true.
The capillary force being independent of un does not imply that the capillary force (or overall "the results") is independent of capillary pressure.
However, the fact is that capillary forces are only slighty changing with capillary pressure - and whatever the sign of un. This can explain the similar void ratio-log p.
Anyway, this analysis is pointless as long as capillary effects are negligibly small.
