What?
Nobody is interested in photorealism.
These newfangled applications like Maxwell don't make photorealistic images - they are too good to be real. If renderings were novels, then Jorge Luis Borges would be the CG Architect award winner forever.
We all want "lo real maravilloso" -- Magic Realism. We want the application to tweak the truth, making soft silk beauty out of our swine barn.
To this end, an application that lightens, saturates and otherwise texturates is going to win because it covers over modeling weaknesses that photorealism examines in detail.
