FWIW What you typically see in the collection cup is mainly particulates eg bacteria,algae etc. Which IMO is also good to remove from tank water. But lets remember that DOC is colorless. So it is very difficult to know (without proper equipment) how much DOC is actually removed. Therefore this is where bombardment rate and contact time plays a role.
Let not get to hung up on how dark the skimmate is.
Just my opinion
Sorry for veering off.
