I’m one of those who don’t care and it annoys my friends. I can tell the difference when comparing setups side by side but when normally watching content, a lower quality doesn’t bother me unless you literally can’t read the words on the screen so anything over 720p is usually good enough. Maybe other people have different thresholds.
It’s also about priorities. If you consider portability good, then no sound system will ever beat your laptop speakers just because they are already on your laptop. I assume it’s the same for people watching Netflix on their phone.
