I think I am on the same page as you.
On 2 occasions in my career I have seen NOTAMS issued temporarily raising the required viz for a CAT I ILS (probably some problem with the ALS).
On both occasions in briefing it became evident that the PF (captain on one occasion and FO on the other) was simply going to rely on the company SOP of sighting the approach lights at the minima in order to continue the approach.
Company SOP's are great but they do not help in such a situation, you still must assess the viz is above the min required.
