If the O-rings or X-rings are working, nothing will get in, otherwise the factory lube would be leaking out. In my experience lubrication is needed for what we've talked about with respect to the plates and pins externally. However it does nothing meaningful to prolong the internal life of an X/O-ring chain. As shared above, if the X/O ring is letting any lubrication in, regardless of brand/thickness, the lube the factory put in there is getting out too. Factory Lube is a thick white lithium grease for lack of a better description. Nothing that can wick in would be beneficial to mix with that. At that point nothing good is happening to the chain.
Lubricating chains was necessary back in the day before x-rings and o-rings. That was the only way lubrication could get to the critical areas that take the most stress and wear. Not the case at this point with X or O-ring chains.
The "red rust of death" is the sign a chain is overdue if not immediately due for replacement. That's when the internal lubrication has come out after the O-rings or x-rings are beyond their service life and the pins/rollers internally are wearing on themselves to create the rust dust. This is typically after quite a long time of happy chain life. I have seen it once, at 33,000 miles on a top tier X- ring chain on my ZRX1200. Lubrication every day on the road trip at the time was the only way to deter the dust. However, the chain was done.
X-rings in my experience are worth every penny when it comes a chain, and external lubrication is really a byproduct of the past with respect to how big of a job it used to do compared to how little it does today.
This was mentioned earlier: lubricating a modern chain is about lubing the rollers and, subsequently, the sprocket. The rest of the chain is sealed, and nothing is getting in.
