that is very very very close. To me it looks like the back wall is a
little brighter in your image, maybe the green wall as well. However,
this could be attributed to the mismatched color bleed. 

that is very impressive.

Hmm,

It seems to me that Pov still isn't putting enough colour bleed onto the
cuboids from the red and green walls. I wonder would it be possible to add a
bleed_amount variable that increases that amount of colour bleed in a scene
without necessarily increasing the brightness of a scene?

As I understant the gray_treshold does just that but it seems that
the color bleed travels too far. It's possible to get fairly correct
amount of red bleed with 0.3 but then the ceiling gets too much color.

Try RadQuality=1 first, it's good enough and fast.
