Arnold renderings not matching color of texture maps

[CreativeFRV]

I cant seem to get my renderings to match the color of my maps. 

I'm redoing a job from some time ago. Back in 2014 when I used Mental Ray (sure miss it). Now I'm using Arnold and struggling with color consistency. I'm hoping this is a simple setting that I'm missing. If anybody can shine some light on this for me I'd get very grateful. Thanks!

Attached are screen shots of what I am seeing. I'm using a very basic Arnold Standard Shader with a very low specular. I've not made any other adjustments. The lighting consist of an environment map that has no color, just a simple studio map and two quad lights. The lighting is a bit hot as I'm trying to get more color out of the render but the blue is just coming in way to dark. It's important that I match the clients blue as closely as possible. Arnold is letting me down yet again.

Well, after a day of banging my head I just realized it's prob gamma... and yes, it would seem that was the problem. Hopefully this will help others with the same problem. Preferences/Gamma and LUT/Enable Gamma/LUT Correction mine is now set to 2.0 and it seems to be producing a render that is quite close color wise to the maps I'm using.

A good tip for the future is using the Render Message Window. Those errors and others will appear there.
