"Not trying to be argumentative. Just a simple question. Have you scoped the cylinders in the last 24 months?" and then what? If its running fine, not burning oil and you are already doing the right things, what are you going to do at this point? If symptoms start appearing then you deal with it. There are enough less important things in life to put on our plates and to worry and be anxious about.
Just budget for a rebuild at some point, hopefully over 100k miles and many years of ownership - given the price of the new ones and E-trend it may not be a bad "investment" down the road assuming it brings you some entertainment/joy in life

Depends on what is shown on the borescope. It's the only conclusive way to determine if you have a problem or not.
You have to chose to be either proactive or reactive. You seem to be a more reactive person; therefore, I "choose" to ....

Absolutely, I did. But the M97.20 Cayman engines are not prone to cylinder bore scoring like the M96 and M97 Carrera engines.
I also scoped my last 996 Carrera when I learned about the problem with M96 engines. I did have some scuffing, but NOT full blown cylinder scoring. Thank goodness. Now, since I had the very early stages of the problem, I switched oil to one that had a better anti-wear package and drove the car weekly to keep it exercised. I also changed out a bunch of other stuff proactively.

Are you referencing the same (996) car and do you still have it? If not, did you disclose this when you sold it ?

My 997.2 MA1.01 was a Florida car with 33k miles when I bought it in February, 2021. Pre purchase inspection noted some minor issues which the shop repaired but bore scope allegedly showed no scoring and the car had a clean over rev report. This spring, 6000 miles and 2 oil/filter changes later, we found non-ferrous metal particles in the oil filter and significantly more in the sump. Bore scope showed scoring in all cylinders, most severe in 1 & 3. Engine most likely requires full rebuild but many parts are backordered. Neither the body/suspension or engine showed any typical signs of abuse or neglect and full service records from 2009 showed regular 6 month oil changes, often at 1000 to 1500 miles or less, and all required service yet here we are... :-(

Interesting and important information. But it always shows that a filter inspection and oil analysis is necessary for a complete assessment. One can neither rely on noises nor on frequent oil changes. You take advantage of preventive medical checkups and blood analysis for yourself, but one often don't let your car get that :-)
