It looks to me like you have as many photons as you need; adding more
photons will only increase the resolution of the bright spots, it won't
brighten the dark areas at all.

If it looks different in real life, then maybe you have your ior set
incorrectly (too high?) or maybe it's due to scattering of the light within
the liquid, which could possibly be simulated by adding a small-scaled
normal to the liquid's surface.
