I changed the oil on my 2018 CX-9 yesterday.
Oil level check after letting the car sit for about 12 hours. Did a pull, wipe, reinsert, then pulled again and took the picture.

After 30 mins of driving, this is the oil level check 6-7 mins after vehicle shutdown (as recommended by the manual).

It's a little hard to see, but there is a difference in the oil level shown on the dipstick.
So what does this mean? Well, IMO it means that reading your oil when cold results in a higher reading than when the oil level is read according to the manual. So let's say the dealer were to do an oil change following the procedures in the manual, then top up the oil so that it's right at the "Full" mark. Someone who checks the oil while cold might think that the dealership overfilled the engine, when they actually didn't.
To be fair, judging by the difference in levels, the "overfilled" amount is nothing to be concerned about IMO. This also means that if you do check your oil level when cold (and top it off to the "Full" mark when cold), then your oil level when read according to the manual would actually be a little below the "Full" mark. Again, nothing to be concerned about.
That's my interpretation from my experience with my engine.
