If a scene has been filmed in this setup, how easy is it to separate the physical foreground from the background screen if they want to re-composite the foreground with a more detailed rey traced background?
The system allows you to insert a dynamic greenscreen around a foreground element (while also retaining the option to preview how things will look after everything). So you can retain most of the virtual set for reflections and lighting, while still having a greenscreen.

I imagine with the advancements in consumer level tech with portrait mode in cameras and zoom backgrounds that the tech ILM has could make easy work of this.
Imagine if the screen flickered at 120hz and half of them were green and the other half were the cgi, and you were able to capture and separate both.
Imagine having to act in such environment... :P
shutter helmet to save you, like active 3d glasses.
After it is filmed, they can still go back and touchup the backgrounds. Someday with ray tracing they can do real time finished products, but for now the tech works great at what its intended to do.
