I think it is more a matter of the render engine. You are used to what P7 puts out and are tayloring your newer products to the older standards. If that's what you like, go for it. I couldn't STAND Gamma Correction until they got it sorted out and SIMPLIFIED in P9.

Sidebar, if you can see your way clear to upgrade, then you will see the advantages of the newer shader trees. They produce some awesome results.
