I think your contact in Michelin is probably spitting out the corporate drivel he has to for legal reasons.
Obviously the sales people will tell you anything to sell you something.
But at the end of the day, the tyres have to meet legal requirements to get the stamps on size, load rating, speed rating. The only differences otherwise will be the tweaks Ferrari have made, which, from what I understand most K1 tyres will have less tread to reduce weight, and the compound/pattern may be slightly different to be more suited to track/hard driving. Any improvements they make there will be a bonus to you... its not like they have microchips in the rubber which change how the tyre acts when fitted to a Ferrari....
I think you may be overthinking things
