AVPlayer is a system player component delivered by Apple. It provides best efficiency, performance and system integrations, but number of playable videos formats is limited. This means for Invidious/Piped videos the maximum resolution you can play with it is 1080p. There's no way to play higher resolution files as they are not provided in the right formats. Obviously, modern Apple devices are more than capable to hardware decode and play these formats. And in fact, Apple seems to be giving special entitlement to Google that allows them to enable VP9/AV1 formats decoding. Just remember that next time you hear how Apple treats all developers equally.

At the turn of the 20th century, dental researchers noticed that many people living near high-fluoride water sources had splotches on their teeth, a condition called fluorosis. Once scientists began studying the effects of fluoride on dental health, they realized that, while fluoride can damage teeth and bones at high concentrations, drinking water with low levels of fluoride actually prevents tooth decay. Today, many cities add a small amount of fluoride to their tap water — about 0.7 milligrams per liter (mg/L).
