"have just small patches of information that are missing or blocked out".

That's what Solar means by being unable to evolve into full Omnisicence. There's the possibility that the information is one that you CAN'T really achieve at all. I'd say Nigh Omniscience is definitely stronger but do you really want to live in a world where you already KNOW (mostly) everything?
