The color space puzzle

Obviously, CorelDRAW allows to choose the desired color space, so the RGB coordinates are defined within that color space. Now, on a Dell computer, you have to select a color space for the screen in the app Dell PremierColor (and you can even select different color spaces for different programs). The effect of this is that the same color space in CorelDRAW appears differently depending on which color space I select in Dell PremierColor, so ironically, with all that "control" I have no clue anymore, with which color space I'm actually working.

AdobeRGB in CorelDraw looks different depending on whether sRGB or AdobeRGB is set in Dell PremierColor, and the combinations sRGB in CorelDraw and sRGB or AdobeRGB in Dell PremierColor look yet different.

So the question arises, which color space should I select for my screen in both applications to have CorelDRAW actually show the proper color space I selected there? When I'm working with AdobeRGB, should I match the setting in the Dell app with it or even select the full screen color space in order for the screen to be able to show the full range of colors, or does the Dell App just assume everything is sRGB, and choosing AdobeRGB would do the same transformation twice, so do I need to choose sRGB? Or should I select the full screen profile in CorelDraw and choose the approriate color profile in PremierColor instead?
