You still need the flight visibility specified in the approach, if you are
below DH/MDA, don't you?


Absolutely, and continuously until touching down.

Let's say the required vis is 2 miles. Reported weather is 3 miles, and
sure enough, you spot the field 3 miles away. By the time you're on 1/2
mile final, it starts to rain and the visibility goes down to 1 mile, but
you can still see the runway clearly. Are you really required to go missed
at that point?
