The check engine light will only come on when an issue is effecting the emissions. I subtle misfire occasionally will not turn on the CEL. It would need to misfire more.
A dealer equivalent tool can check mode 6 data which shows the past 40 starts and all the history about the vehicle in those 40 starts and drives. Also the same tool can run a power balance test to show you which cylinder is producing less power than the others while monitoring when this issue is occurring.
