I use my personal understanding, and I think so:

Beauty has a wide meaning, and it can be used to describe many things, such as pictures, scenery, things, music, appearance and soul. His meaning includes beauty, but it also includes beautiful, pleasant feelings, visual enjoyment and other meanings. The profound meaning of beauty is beautiful in mind. That means morality and self-restraint.

and beautiful, can only describe the appearance, for example, this thing is beautiful in appearance and people are beautiful. There is also a saying called "well done", which only means well done.
