ELI5 : why are the quality of voice/videocalls so low, when we can stream 1080p++ movies on demand?

Is there real reason why calls are so low in quality (relative to the hardware's maximum capability), or am i just using sh*t platforms?

(I've tried using google duo, google meet, zoom, line,whatsapp etc and their quality doesnt differ much)

.

Additional question : is there a platform that focus on super high quality calls?

Your movies are streamed trough protocols built upon transmitting high def video, and if you force high quality, your.movie will stop and buffer until enough data is downloaded to continue.

A video/voice call uses a very different protocol, built so that communication happens in real time. On top of that, your same call service has to work for those poor kids in rural africa, to make an extreme example, so it uses adaptive audio and video quality for that purpose.
