The TV frame should already be black and the images on the screen (for hockey) will not get any brighter so there's no way to use black velvet or some other fabric to improve perceived contrast. You are talking about a display technology that will produce, say 35 fL for the hockey ice if you make the image fill only about 10% of the screen area with the rest of the screen black. If you then enlarge that image to fill the entire screen, you are only going to get about 17 or 18 fL for the white ice. You can't stop that nor can you make the contrast seem higher by some trick.
It MIGHT look brighter if you sit closer and have the image fill your field of vision more completely, but you can't get TOO close or you will start seeing the pixel structure. Projection screens look plenty bright if you can get 16 fL... that only works because the projection screen is usually quite a bit larger than a flat panel display and the screen fills a larger angle of view than a flat panel in the same space and seating distance. You can kind of simulate that with a panel display, but it involves moving closer to the panel to increase your viewing angle. There are viewing angle calculators online that you can search for. About the largest viewing angle you should attempt would be 45-50 degrees. In the viewing angle calculator, enter the width or diagonal size of your display (as required by the calculator app) and vary the seating distance until you get somewhere in that 45-50 degree angle range. If you can see too much pixel structure in the images a that distance you might have to back-off to 40 degrees but that will also make the "brightness" effect smaller.
