It also depends on the type of driving that you do. I do mostly city driving, with short trips especially in winter where my engine (let alone oil or tranny) rarely reaches full operating temps. That's harder on the oil so it should be changed more often.
The tech at the dealership said never to follow the EVIC for oil life, but I also assume that his bosses want the extra oil change money. Below is what the owners manual says for my 2015. I do tend to trust the manufacturer more than any dealership or folks on the internet. If they say you can go up to 10,000, I wouldn't worry about getting there unless I was driving under harder conditions (which I am) so I change more in the 5k-7.5k mile range.

exceed 10,000 miles (16,000 km) or twelve months on

exceed 8,000 miles (13,000 km) or twelve months on
