Would be interesting grant work to figure out the answer. I know it is present in most if not all tanks. The UV will certainly limit it from any sort of fish to fish transmission, and wipe out the free swimming stages. However there are non swimming situations on and off fish as well as the whole encysting aspect of their life cycle. I have seen tanks that without an introduction of new fish for 6 yrs or more- got ich after a power outage. Fresh and salt water- which is odd considering the differences in the morphologies, but true just the same. WIth proper QT you allow fish to be gently transitioned from wild to final captivity. the proper treating of parasites in QT along with proper non competitive feeding will allow for a stress free introduction to a new tank and a much lessened likelyhood of ich in the display.
