Yes, but PAG already has already made the decision to allow the car to rev to 9,000 rpm from the first mile (some brands have a lower rev limiter during break-in) and provided no warning of lost warranty in the owner's manual if one doesn't observe break-in. What the dealer says or writes is irrelevant on this issue.
In general, your advice is good to take a salesman's comments with a grain of salt though.

Managed to stay below 7000rpm for the whole run-in period. Actually the car is so entertaining at low rpm also so it wasn’t a biggie. Now it’s all Rock’n’Roll🥳🥳🥳

thank you I hit 7k once so far 150miles. I got a long way to go prob gonna take me few month haha. Loving it so far. Not as ruff as was afraid based on review and noise level is very bearable to 7k.

PMNA told me numerous times on GT3's and on GT4 Clubsport there is no running in period.

In my opinion they recommend the break in for the driver to get used to the power and traction of the car. Legal had a hand in drafting it I’m sure. Everyone has their own appetite for break in but these engines should be ready to go on day one, just make sure they are up to operating temp, if they weren’t it would be a mandatory break in with warranty implications. Just my 2 cents.

I just picked up my car from getting full Xpel yesterday and looked at the manual for break in miles. The U.S. manual says to keep it under 4,000 RPM for the first 1,875 miles! That seems excessive and is twice what my 992 GT3 break in miles was (982 miles on GT3).

And now we will hear again from all of those who think otherwise.
In the end it is your choice.

4,000 rpm on the GT3/GT4 RS motor is extreme (I'll let people decide for themselves whether it's extremely excessive/unnecessary or extremely protective)

There are plenty of people who won't even own the GT4 RS for 3,000km. I wonder how many of those cars will be kept under 4,000 rpm.

I saw a video somewhere explaining the 4,000 rpms max suggestion. The goal of the Run In period for Porsche is to avoid heat spikes of the internal metals during the early life of the powertrain. Some metals expand more rapidly than others. Porsche determined that at 4,000 rpms or below you could not heat spike your engine. So it is not an absolute, just a place where they can put in the manual to assure you of no heat spike. It was explained that such heat spike could lead to premature wear over the very long run. So my take away is avoid driving that causes heat spikes, such as scaling mountain roads, or idling on the tarmac in 110 degrees, or performing a launch of the vehicle.
Same thing on the mileage - they figure you will encounter enough heat cycles at the suggested 1,850 miles. But it is not absolute. If you did a cross country trip and only stopped for fuel, you may only experience less than 6 heat cycles. Whereas, if you did a bunch of 1/2 hour trips, but only covered 500 miles, you may have twice as many heat cycles.
