3940G-025 (roman) dial change to 3940G-013 (classic) - Value impact

Hi All,
I have been searching for a Patek ref 3940G for more than 2 years now and have just viewed one full set, mint, late third series (2006) from a friend of a friend who is selling it.
While the watch is currently showcasing the "classic" 3940G-013 dial like this one :

, the watch and papers originally state that the ref is a 3940G-025 (https://images.app.goo.gl/kR9BsQkKWArEwk8y7) with roman numerals. The dial change has been done by Patek itself, and as always, they kept the original dial when making the change.
My question is: while the watch is in perfect condition and that the dial has been changed by Patek itself, which kind of value impact (if any) should be expected on this one ?
Not here to flip the watch but to wear it, but keen on making an educated purchase!
Many thanks for your answers !
Paul
