you seem to be having together do the work of quality; were i to say "what about time together with a friend distracted by their phone?" you could say "oh, that is not quality time" or "but you aren't really together"
nothing wrong with contemplating whether these things are the same or different, just pointing out it can be hard to sum up complexity with single phrase aphorisms
There is no such thing as "quality time", only "time" (together).
