Linear Workflow switch

MY god..!! this is getting more complicated…!!

So basically whatever settings I am using in this image - ImageShack - Best place for all of your image hosting and image sharing needs
is wrong?

I have to keep GAMMA at 1.0 if I am using EXR, is it? I am using EXR, however I am not encoding the gamma into the image, I am just using gamma 2.2 to view the image.

I tried switching off and on, the LINEAR workflow button and got these result ImageShack - Best place for all of your image hosting and image sharing needs
