Yes, the zenith distance at upper culmination is less than the zenith distance at lower culmination. The zenith distance is the angle between the zenith (straight overhead point) and a celestial body. At upper culmination, the body is closest to the zenith, resulting in a smaller zenith distance. At lower culmination, the body is furthest from the zenith, leading to a greater zenith distance.
