This is also an issue on desktop web. YT will arbitrarily change the quality/resolution but doesn’t update the selector displayed in the UI. So for every single video I have to select 4K just in case YT might be serving it at 1080p or some other resolution even though it displays “4K” on the UI element.
Also the compression algorithm is very aggressive and it works reasonably well for general content but for edge cases (like starcraft streams), the 1080p loses enough details to make it hard to see important things like observers and outlines of individual units in crowded clusters. The compression algorithm just isn’t trained/tuned for these types of content, so even on a 1080p screen I need to stream at 4K just to see the details properly.
