4k does make improvement in vernier resolution (fine discrimination of object position) even at regular viewing distances, but trials show that this is not as noticeable an improvement as high dynamic range and, secondarily, wide color gamut. So, 4k may be broadcast simply as a numbers race, but it is likely that the real visual improvement will be HDR, which ATSC 3 will also enable.
