Generally parametric EQ will get more exact. You can configure AutoEQ, increasing the number of bands beyond 10 and tell it to attempt narrower corrections.

The measurements are not entirely accurate, particularly in the treble, and some aspects of the measurement will be different on your head, so extremely close adherence to a target from flawed measurements is not a great idea, small stuff it’s usually better to leave alone. Hence why by default it won’t make very narrow corrections.
