If a modern forger were to mix the inks in the correct way, there would be no way of telling surely. 

Indeed, though it is more often a problem with the pigments than with the inks. Forgers from that time frame made those mistakes because they did not know then, what forensic experts know nowadays.
As time went on, the forgeries became better and better. Book forgeries have always been extremely rare, and paintings were a much more popular target.

It's think it's important that the findings are not interpreted as proof of the 15th century creation.

This has always been understood.

The problem is even bigger, because in some cases, modern pigments in genuine old books can be the result of ill-advised restorations (not to mention retracing....).
