I suspect the optimal clamp to wash out color too much. is it possible to preserve color with clamping method that just address unwanted fireflies and useless noise.

More test comparing now bidir with pathocl/metropolis. I don't know if this is normal but path renderer produce flat lighting the directly illumination and the indirect illumination are a bit blended. Bidi produce a more correct lighting which result in a deeper 3d impression. But i think the defference is to high.

You are using clampling so the the output can not look the same even from a theoretical point of view. However the ceil lamp in your PATH rendering looks wrong. Try a PATH+SOBOL rendering does it looks the same ?

I'm on the workstation of the office (2Xgtx titan black) and opencl gpu is to instable so i go for path cpu sobol without clamping. as i said the lighting is wrong.
