Here's a nice little article with some details:

This isn't entirely accurate. Nspec tires can and do often vary from non-Nspec versions of the same tire. Porsche worked with the manufacturer to tune the tire to Porsche's preference. These tires are potentially slightly physically different from non-Nspec versions.

This is true. I can’t remember what car it was, might have been an old 2012 M3 I had, but had to get a single tyre replaced on the rear (less than 1k miles on them).

Tyre place put on an N spec instead of star rated, same Michelin PS2, it looked similar but the tread blocks we’re in a slightly different pattern and it has slightly more rounded shoulders. Car crabbed slightly, wasn’t good!

It got sorted pretty quick, but does prove to me the manufacturer rating isn’t just a badge printed into the tyre wall.

Has anyone been able to get a set of N rated 4S then? I keep checking UK suppliers, and no news so far.

Now, that's not saying you will see a major difference over the non-N spec tire. It may be slightly quieter, or stop slightly better, or stick a corner just a little more - but there is a difference however subtle.
