Naruto did not have the actual juubi inside, he was simply able to recreate a fraction of its chakra. This is proven by the fact that he could still speak to individual biju throughout the fight with kaguya. So since he doesn’t actually have the juubi inside him, he doesn’t go through the same changes as obito or madara,

Or, it could be due to the lack of the Gedo Statue. Naruto doesn't have the Gedo Statue and that could be attributed to why he doesn't resemble the other Ten-Tails Jinchuriki. He has the power of the Ten-Tails but not the actual Ten-Tails.
