Advantages of varying between barbell AND dumbell versions of the same exercise?

For example, if I always do barbell OHP on day 1 then dumbell OHP on day 2. Barbell upright row then dumbell upright row. Barbell curls then dumbell curls, barbell bench then dumbell bench etc etc.

Would it have the benefit of hitting same muscles in a different way somehow or induce more hypertrophy because of constant variation? Or it doesn't really have any substantial benefit?
