I would expect the sensible cooling delivered to the zone to be very close, but not the total cooling. If the sensible loads do not match, then check to see if both are actually meeting the zone setpoint.
For latent, it is more complicated. The VRF is controlled to meet the zone sensible cooling load, and the latent cooling will vary depending on the current conditions and part load. The ideal loads system has four options for dehumidification control (ConstantSensibleHeatRatio, Humidistat, ConstantSupplyHumidityRatio, or None). None of these will match the VRF performance.
