No. If you have standard definition cable tv service, the picture is good, but not really any better than with a non 4K tv. HD cable the picture is awesome, but it is not 3D. If you have a Blu-ray player that is 4K and 3D, playing a HD disc, the player upscales the picture on the TV to near 4K quality. 3D discs played on the 3D Blu-ray player (with the 3D glasses included with the TV) are great, with the 3D effect as good as at the theatre.
