YouTube may make 4K video viewing on the platform exclusive to YouTube Premium subscribers, according to screenshots posted by users on Twitter and Reddit.

In the YouTube app on iOS, and probably on other platforms as well, the service began to show a message that to watch videos in 4K, the user must be a paid YouTube Premium subscriber. So far, such a message has not appeared for everyone, and the 4K quality option is still available for most users. However, given the deteriorating forecast for parent company Alphabet’s revenues, as well as its plans for 20% efficiency increase, it would be logical for YouTube to transfer some of the advanced features of video hosting to a paid subscription.

The basic YouTube Premium plan for one user costs UAH 99 ($11.99 in the US) in Ukraine and includes ad-free videos, background playback, and the ability to download videos for offline viewing.
