Hi.
CineRender settings are really similar to Vray's. The most probable thing you are seeing is reflection rays being cut off.
In the CineRender settings (not the surface parameters), enable detailed settings, go to options->general options. Lower the threshold value from 15 to something like 3. You should now see reflections with lower values.
For blurriness... well... it looks that reflection values and blurriness values are tied together, so use very low blurry values and control reflections using a map, maybe a fresnel or falloff; and remember to give it more min samples, so blurry reflections are smoother.
Also, as a general note, when fine tuning reflections, give your surface something to reflect... just place a couple of objects at a certain distance from you camera so you can see the effects.
Hope that helps.
Best regards.
