Japanese bullet train "Nozomi" Nagoya to Osaka

I rode the Japanese Bullet train from Nagoya to Osaka in June and thought it was the Nozomi train. I heard it may have been a different train based on the color banner displayed outside and wondering if any experts here to comment. I think it was the fastest train on the route and the a JR Pass was not permitted. Is the Nozomi the fastest train from Nagoya to Osaka? It made one brief stop in Kyoto. I made a youtube video to capture the moment and can't wait to go back to ride more trains within Japan.
