Just bought a Samsung TV that had identical issues. For the most part, you'll just have to live with it. However, I noticed that a lot of the light bleed is due to the trim around the edges of some samsung TVs (not all, depending on models) is pushing against the screen, which is letting more/less light in around the edges. You can try bending the plastic bezel/trim away from the TV but usually it will just revert back, but my temporary option was putting little bits of micro fiber into the trim to "lift" it away from the TV. It removed the most noticeable light bleed. Isn't the best solution, but worked well to reduce most of it!
