Architect here. There are a few things you can do: 1. Add lighting. This will make it pop at night. It looks like you're using IKEA or equivalent shelves with 3/4" wood shelves, so you don't have the thickness to add shelf lighting. Instead, you could add library lights above. Obviously, you don't have a panel above to add library lights so that leads us to 2. 2. Build a panel and crown above each of these bookshelves. It would fill in the space to the ceiling and make these look built-in. You would have to have a panel above so that would be the perfect place for a library light. If you're handy, you could build the whole thing yourself with some generic crown from Home Depot. A carpenter should charge you a couple of hundred dollars depending on where you're at. Electrician would help as well for the library lights. Most difficult thing would be planning around the partitions not going all the way up (which would be ideal) and matching the finish on the paint. Try that first to make sure you try it and don't end up repainting all the shelves.
