GPIO out voltage level

Hi
I did configure the USR1 GPIO with a high drive strength.
My V_supply is 3.3 volt.
What is supposed to be GPIO voltage ouput? 3.3 volt or 3volt?
I was expected 3.3V but it seems to be 3volt. Is that correct?
Thanks

Expected output is VDD. Max current load is around 15mA at highest drive strength..
