ehh not really, throw ups are different from tags which are different from murals - muruals often aren’t graffiti because they require more time, which tends to require permission
Basically the difference is that the mural is bigger and probably has the building owners consent, but in terms of aesthetics it's a tossup. Most murals seem to be abstract visual noise that is scarcely better than average graffiti, and on the other hand some rare graffiti is far above average. And then there are the murals with a message, which often end up looking like Soviet propaganda posters (or in fact murals, since the Soviets were big on murals too). Huge images of some local leaders linking arms with workers to deliver symbolic world peace or some tacky saccharine sweet bs like that.
If I'm being honest, a lot of these Soviet murals actually demonstrate superior technical skill and aesthetic understanding than the murals in my town (many of which aren't worthy to hang on a mother's refrigerator): https://www.amusingplanet.com/2017/10/the-forgotten-soviet-e...
Throw ups are different to tags but I still don't think that explains how graffiti is distinct from mural, unless you're trying to say all graffiti is unsanctioned, which... isn't really the case.
