If the bricks give you the feeling of a dated fireplace, painting them white may not solve the dilemma for you. The light color would blend the fireplace with the wall. I took a look at your pictures and the sitting area in front of the fireplace has a fairly transitional style. Since the walls are light, I would replace the bricks with a premade wood mantel to create a focal point. I am attaching two mantels that I believe would let you achieve your goal. One has straight lines and the other has a similar style to your console table. In my opinion the dark wood and the straight lines would harmonize with your sitting area and area rug better.
Beautiful house!
