Naruto doesn't have Uchiha eyes. Even if he has the chakra, it won't affect his body(eyes) the way it would an Uchiha. Unless Hagoromo makes it so.

It's the same reason Madara didn't have any Sage Mode when he unlocked the Rinnegan.

Hagoromos power was basically forked. Getting his chakra doesn't make someone have all his abilities, it just amplifies the power someone had already based on their genetic line.
