Cruise control using higher RPMs with CVT

I have a 2019 kia forte with 2.0 and CVT. I recently tried using cruise control on the highway at about 60mph. While in cruise control the engine speed was adjusted to about 400rpm higher than where it was when I was manually controlling the engine speed. I figured this could be because the computer knows this engine speed will yield greater fuel economy. Unfortunately, after testing the theory several times, this is not the case. I have a 10 mile commute home from work on a stretch of highway that has barely any traffic. On board computer, scanguage, and torque pro app all report same. Im going to be taking a 1000 mile trip soon and would like to use cruise control but not at the expense of fuel economy.
Anyone else experience this? Have thoughts?
