Measuring input-offset-voltage of an opamp in sim and getting very different result in datasheet
Yes - your simulation profile is correct, provided you have sufficient resolution in the transfer region (at least 3...5 data points). This can be verified uisng the slope of the transfer line, which roughly must be identical to the open-loop DC gain.

Please note that the given figures in the data sheet are typical values only (since the offset voltage is a kind of tolerance parameter), which can be expected. Hence, an actual value of 35µV for a given specification of 2mV is within specification (and very good).

EDIT (comment): You cannot expect to see a parameter EOS in the model description. This would be the case for a 100% symmetric opamp model only. However, most opamp models contain realistiv transistor models which are NOT symmetric by nature. Therefore, you cannot expect to have zero output for zero input (symmetric supply). This effect creates a kind of unsymmetry which determines the offset.
