Need ICC Profile enabled after hardware calibration?

I apologize if this isn't the right thread, I just joined a few min ago as of writing this 

So after hardware calibrating my Dell U2413 using the Dell Ultrasharp Calibration Software (1.5.3) with an i1 Display Pro successfully, it saved a calibration Lut to the hardware under Color Space> CAL 1 (srgb, 120 cd/m^2)

The Dell Ultrasharp Calibration program also made an ICC Profile for the third step and asked me to save it

so my question is do I need to have this ICC enabled for "Use my setting for this device" for the colors to display properly or I can turn it off and the colors will still be displayed properly? 


I didn't have an ICC Profile on before calibrating if that helps anything
