hello, some thing wrong in your sim, please show the setup and results, in most of the cases you would need small signal gain, so please connect in unity gain configuration and apply vdd/2(or some reasonable common mode) at the non-inverting terminal and find the loop gain.don't sweep input voltage for such a wide range in open loop it might saturate.
Keep in mind that large signal gain will always be grater than small signal gain.
Thanks, Raj.
