The sharingan and Rinnegan both give the ability to see chakra. The Sharingan can see every minute detail, including handseals. So, the sharingan gives great insight into a jutsu and so allows the dojutsu wielder to easily copy them. Copying jutsu is not an actual power of the Sharingan.

The Rinnegan gives insight beyond the Sharingan, which makes it easier to master even more difficult concepts like elemental releases. Nagato easily learned any jutsu Jiraiya taught him and mastered all five elements with little trouble. Like Sharingan, Rinnegan does not give this as an ability. It's insight and ability to see chakra simply make it really easy.
