Pretty much, yea. His eye is a Mangekyou Sharingan and Rinnegan in one. The tomoe simply indicate his Mangekyou powers are present. With a plain design he can't use Susanoo, with the tomoe he can.

The plain rinnegan.. i can't remember exactly what happened in boruto the movie (only seen it once). but didn't sasuke say his rinnegan need to recharge in order to use the teleport ability to other dimensions? also when reading back in gaiden, i noticed he used amaterasu from his rinnegan with no bleed side effect which is pretty cool. okay, so now i'm a firm believer that the tomoe rinnegan is just access to using MS ability. the only think that bothers me, what is the explanation for madara's use of susanoo without any eyes? i can't defend your tamoe rinnegan = MS ability, if i can't explain the inevitable madara no eye susanoo questions.
