Panasonic G85 from an Olympus user

If my question is noobish.. please excuse me.

On my G3, it allegedly has a 'live view' mode which to me means that the camera adjusts the view through the viewfinder to be pretty close to what the final image would be (in terms of shutter/exposure)and so forth. It is a selectable Fn button (Fn2?)... which really does not seem to work as advertised.. so I keep the button assigned to AEF/ etc.

(FYI.. as an example on my G3 when I look through the view-finder with my Olym 25mm f1.8 attached, I can see the aperture is set to near f16/f22 so the image that I see through screen will NOT be the final result)

Whereas with the handy-dandy 'training videos' that Panasonic has released, there is a apparently a far clearer mode of seeing (via viewfinder or rear screen) What You See Is What You Get.

And my actual question becomes - "if you have that (above mentioned )feature available to you AND you can see a really good approximation of your final image, why do you then next to have Exposure Compensation in Manual mode, when you can adjust your I, A and S settings really easily?"

Not sure I follow most of the above and can't be bothered to dissect it and tackle each issue individually. What I can say is that the viewfinder and LCD of most mirrorless cameras will only display wysiwyg around three stops either side of 0ev. Beyond that range you usually get a coloured or blinking warning of incorrect exposure along the bottom of the display, if you have setting display enabled [toggle the Display button until you get it]
