ADA4895 SPICE model accuracy


The open loop response I'm getting from the ADA4895 SPICE model does not look very realistic when compared to the datasheet.  Besides the dominant pole all I see is a single pole-zero pair around 1 GHz giving a phase dip down to about -145 degrees before returning to -90 deg at higher frequencies.  I was thinking the model would be fairly detailed since the netlist includes a bunch of additional poles and zeroes but on closer inspection it looks like the three additional poles and three additional zeros are all just stacked up at 1 THz and have no effect on the response.  Is that intentional or did something go wrong when generating this model?
