I love bookshelves as well, and one way you can make your bookshelves look more aesthetic while still using them to store your books is to get rid of all the books you don't need/want and filling the extra space with minimalistic/clean looking decor (so it doesn't look cluttered). This will be the artistic imagery in the room, so the best object for the space on the wall would be a mirror, which will nicely reflect some light in the room.
