The "objective evidence" you may be seeking, is found in Used Oil Analysis data. But, I really doubt you want to change your mind, or are willing to do so. To each their own.
Additional evidence can also be found from the Porsche specific engine builders who also recommend (and require) an early oil change after their builds. If you're looking for more evidence and support.
I don't need to know everything Porsche, I just need to know the people who do!

Read any of the numerous Rennlist posts from Charles Navarro (who already posted here) or Jake Raby (including his website). They require early oil changes on their builds. If you have better Porsche specific sources, please share. I'd like to read them. I'm pretty sure the same advice came from other builders like Kevin at UMW and Todd from Promotive, but I haven't followed those Porsche guys in many years.
EDIT- I see Charles already responded while I was typing. Thanks, Charles.

Would this be the same for a factory fresh engine from, say, Stuttgart?

The reason for an early oil change is to eliminate flashing, cutting residue, and anything else left in the engine during manufacturing. No matter how hard you try, there will be something left somewhere in the engine. The oil washes everything out, dumps it into the oil pan, where it gets picked up and pumped up to the oil filter. Some does not get picked up and remains in the oil pan. An early oil change will eliminate what's found in the pan and what's found in the filter.
I would do this whether it's a Porsche or a Subaru. It's just good to get this debris out of the engine.
MOO & FWIW

I think anecdotal evidence is always going to confuse people because there's so many moving parts. On one hand you have people that never followed break-in, change oil late, have highly modified cars, and never have issues. Then on the other side you have people who do careful break-in, early oil changes, no modifications, and their engine blows up early into ownership. Neither of these accounts really hold merit on their own because of such an incredibly small sample size. To truly get anything statistically significant would require much more data and that's very difficult to accomplish.
IMO a break-in oil change, even if it does nothing, is a small price to pay as a (potentially useless) insurance policy - which seems to be the point others are making.

Talked to three of my local dealers and two of them are carrying the Mobil1 ESP Formula 0w-40 for 718 GT4.
Also talked to Mobil1 tech lead, and here is his response:
I think we might be able to get the ESP X3 from MB or Audi if Porsche dealers dont carry it. I have some Motul 5w-40 but it makes me secured if I have some access to ESP X3. 
Also talked to Mobil1 tech lead, and here is his response:
Thank you for writing to us. Currently the only overlap between Mobil 1 ESP Formula 0W-40 and Mobil 1 ESP X3 0W-40 is the General Motors Dexos2 spec.
Mobil 1 ESP X3 0W-40 is currently a Porsche "dealer only" item, and is the only one I can recommend under the Porsche C40 specification.

I'm hopeful that this "dealer only" status will change soon, allowing us to also provide it to customers of other manufacturers as it also covers specs for Mercedes, Fiat, and Audi/VW.

His reply states it is NOT available through other manufacturers such as Mercedes, Fiat, and Audi/VW.

So from what is stated in this thread there seems to be no retail source for C40 Mobil 1 oil?

Which is what I plan on using when I get mine if Mobil 1 doesn’t become available and even then, of the 5w-40 isn’t in the mix I’ll probably stay with Motul. It get pretty hot here in FL

I believe technically the dealer is considered your retail source assuming they choose to stock the bottles and not just the 55 gallon drum. Yes, it sucks but you always have the option of the 5W-40 Motul that is available through aftermarket resellers.

Locally I can't get either oil here although my preference is to stay with Mobil 1 oil. I plan to reach out to the dealer next week about a post break-in oil change...
