If you install any filter with out oil in it, it takes 2 seconds to fill.
What you've read is nonsense, no offense intended.
Oil pressure won't change, and flow through the engine won't change either. Flow through the filter will slow slightly, that's good.
A faulty abdv? How often does that happen?
With a good quality oil and filter, even an oversize one, you shouldn't have any worries.
