Looks like there is some discussion about comparing results from Corona to Vray. Google translator is failing hard, but from what I understood you are trying to compare pathtracing to pathtracing. You won't find significant differences there, as path tracing never blurs anything, and your scenes are too simple for any significant clamping to occur.
Nevertheless, there seems to be some difference in creases and dents, with Vray output being more "defined" (darker in shadows). This is not because of some interpolation of path tracing or faking in Corona, but probably because Vray by default completely ignores reflect color at secondary bounces (unless you turn reflect caustics on). This means, that Corona is giving correct results, and vray fakes the result by not computing a subset of light paths. If you turn reflect caustics on in Vray, you should get almost the same, correct image.
