Not at all.
Joseph Smith claimed to have special knowledge directly from God to interpret all aspects of the Scriptures and to even introduce new Scriptures given by an supposed angel.
The Catholic Church's claim is quite different: that Christ gave the Apostles authority to teach - which is attested by Scripture. The Apostles were also able to ordain successors - this is also attested by Scripture. The Apostles handed down traditions to those they appointed - which is also attested by Scripture. The Pope and other Catholic bishops can show that they were ordained by bishops who were in turn ordained by other bishops in an unbroken line back to the time of the original Apostles. Therefore, whenever the bishops teach together on a point of doctrine, they teach authoritatively.
