You can enjoy stars without understanding mechanism or science behind it . Moreover, when you see someone in street, you feel something without knowing anything about it. It is the art of God and you can enjoy it without understanding it. This part is more about senses.
Another idea, should be that pleasure in art can increase through the development of a personal understanding of it. İf we continue with our example you will like more or less someone after knowing them. The idea is same with the art concept. So, truly understanding art not always makes you enjoy more.
There are hundreds of other factors make you to enjoy the art.
One of them is “Making process.
Check mandala art for it, when you see how they are built it, you will love more than ever this art.
Under which conditions they built it is related with time and place concept. For example, if an someone made wooden object in the 2.world war. You will appreciate and have more connection with this object which will make you like it more.
I try to to cover the discussion of “Is it possible to enjoy art without understanding it?” The answer is yes, but more you understand it, the more you see in it.
Tell your ideas about this discussion.
Best,
