'Use Bkg Luminance' and 'Use Bkg Chroma' affect the output color by the new background. This feature can also sometimes really help with screens that exhibit some form of fringing artifact - usually a darkening or lightening of an edge on one of the color channels on the screen. The effect can be offset by grading the Bg input up or down with a grade node just before input. If it is just an area which needs help then just rotoscope that area and locally grade the Bg input up or down to remove the artifact.r
