How does YouTube Premium affect the user interface compared to free YouTube?

YouTube Premium does not significantly affect the user interface compared to free YouTube. The basic layout and features of the YouTube app and website remain the same, whether you are a Premium user or not.

However, there are some subtle differences in the user interface for YouTube Premium users. For example, when you are watching a video as a Premium user, you will see a small "Premium" badge in the top right corner of the video player. This badge indicates that you are a Premium user and that you can enjoy ad-free viewing, background play, and offline downloads for that video.

Additionally, when you are browsing the YouTube app or website as a Premium user, you may see some special promotions or features that are only available to Premium users. For example, you may see a banner promoting a new YouTube Original show or a special offer for a music artist's concert.

Overall, while there are some minor differences in the user interface for YouTube Premium users, the basic layout and features of the YouTube app and website remain the same as for free users.
