Depending on your settings.
When I do use it, I'm hard setting one anchor. My normal would be to hard set ISO, AP and then +/- comp. The shutter speed will be used to lighting the image. If light is still a problem, then I go auto on the iso. There is a priority the cams use. The camera drops shutter until it can not, then ups iso, and then back to shutter. It will do the same to the aperture if SP is set.
That is mostly why I set my cams to using 1/3 stops (even EXP comp), so those changes are not that sweeping. For landscapes, some wildlife, one to two thirds is all I need to correct. The limits is set in camera and you can change them. I allow shutter/Apature to go however then need. I place a limit on how high ISO goes, but I can change that if that needs to be. For sports, I guess I would limit the iso to where I couldn't fix it in post.
This program game would not be easy to "see" the difference. Most of the time, the cam is changing aperture to get that light. Once aperture can't, then the cam goes and bumps iso. You will see the difference when light is low. I would see the difference when it is dusk, when no amount of correction can be done without iso. I don't see much of a difference when, for example, a cloud moves in and changes the light level.
Photography: 100 percent art, 100 percent technical. It takes a photographer to blend them into an image.
Film: That tangible image that you can see and hold.
