3ds max VRay lut ocio burnded into image looks different

Hi Guys,

just a little question,
when i render an image with lut or ocio in the framebuffer set to be burned in the final image,
the renderoutput looks different from when i render locally.

it seems like something has been applied but the images are far from identical.
Is this a bug or am i doing somethin wrong?

thank you very much
