I would not agree for example on epson R3000 even on same windows 7 OS, driver version 1.71 vs. 1.75 has differences in grayscale that is measurable. So there are differences, and it's best to re create the profiles if certification proves there are visible differences.
It's a big deal when an OEM changes the raw RGB -> CYMK inking pattern. This is typically hard fixed in the drivers with identical mapping for driver step changes let alone for different OS's.
This would invalidate existing OEM installed profiles as well.
That said, the drivers do determine the RGB->inking so changes, intentional or not (bugs), can certainly occur. I haven't seen any changes in my 9800 from the days of XP 32 bit drivers to the current ones installed on Win10 x64.
If you have specific data on this it would be quite a service to help quantify and document what you have observed. An actual driver rev change creating a difference in inking would be quite concerning.
