Bitrate per pixel is what we're talking about. Bitrate alone tells you nothing. If you're actually receiving a full as-advertised bitrate stream with a well-implemented compression algorithm then obviously if all else is held equal then higher resolution = higher quality. But in reality many streams are overly compressed to save on their bandwidth and server costs, and often due to tech inefficiencies you won't actually receive the full bit rate, resulting in even more additional compression losses.
Again, a perfectly-implemented, perfectly-transported stream in 720p will always look better than a 480p dvd file. But in reality there are many situations where a stream is imperfectly-implemented and imperfectly-transported, sometimes to the point where visual quality worsens to below what you would get from an upscaled 480p dvd.
But anyway, neither of us are true experts on this topic. If you're always 100% happy with the quality of the streams you see, then that's great! But many of us sometimes encounter streams where the compression causes obvious visual degradations to the point of being distracting. Personally i prefer lower resolution with no obvious compression artifacts, rather than higher resolution with obvious color banding and visual noise in motion sequences.
I am not always happy. But I can also see that a DVD has lower quilted than essentially any YouTube video. Of course unless it was uploaded in lower quality to begin with. The source material has to be good enough. There are more than enough 1080p videos that are only 360p. Or 4K that is only 720p. Not due to compression, just from the source material.
