Different rendering results using CPU (Mac) and Nvidia GPU (Win)

Please note the huge difference between 3 renders in JPEG attached.

Is this something I should expect switching from CPU to GPU rendering?

no kidding... its almost like Nvidia have been the world 3D standard from day one and Apple Mac metal drivers have a Long, long way to go before they even get close... good thing Adobe did their homework before jumping on the metal bandwagon or they would have stuffed all their 3D software in order to keep Apple happy

Not sure what you mean about Metal and Apple, CPU render made on mac is the correct one (in term of lighting, colors, reflections etc). As far as I know Metal is not involved when rendering with CPU on mac.
