overfilled oil
I realized that the dealer overfilled my oil (M272) by about 2 quarts roughly 2,500 miles later. I’ve extracted the excess, and I have three questions:
1. Is there an electronic overfill/ underfill warning in this car? I know that it doesn’t have a mechanism for checking the oil electronically.
2. Has this likely caused damage to the engine/ is there any way to tell? Everything has seemed to run fine, and I didn’t notice any bubbling/ foam on the dipstick before removing the excess oil. How much leeway does the M272 have?
3. I notice the oil level is significantly higher after letting it cool for several hours, is this the level I should be considering? (Instead of five minutes after shutdown as the manual suggests)

I know the manual says that you can check the level after the car has been off for only five minutes, but it seems that this is likely not enough time (at least to fill to max)?

I think I know what happened: they must have checked the level immediately after turning the car off for five minutes and made sure the level was near the max. After removing two quarts and being off for only five minutes, the level is at the bottom of the range. When the car sits over night, this is towards the top of the range.

I dunno how people screws up oil change. It is very simple. Drain the oil and look at how much oil was taken out then check the manual to see the engine's oil capacity then if it evens out refill the same amount. If the oil you took out is same as what the manual states, no need to guess work and do the wait for X minutes thing.

Would an oil examination service like Blackstone likely be able to detect internal damage from this? RPMs were kept low during this period, so I have my fingers crossed it’s okay.

Yes, it is correct that the machine will automatically calculate the oil that is correct for the vehicle, you assumption that they did not completely draining the old oil/or suction out from dipstick for vehicles with a dipstick is also correct, it is a common occurrence from experience.
