Voltage offset test

I am trying to perform a simple voltage offset test in Spice for an
OPA227. I have both inputs shorted to ground, +/-15V supply, and I am
getting 48.9mV on the output. The data*** shows +/-100 uV for the
OPA227P and +/-200 uV for the OPA227PU. Either way, my test simulation
is off by a few magnitudes. Is this a limitation of the simulation or
is there a better testing circuit configuration for op-amps?
