The Macrovision signal was an out-of-image voltage change during the blanking interval. AGC circuits in VCRs that used the blanking interval to set the gain would be thrown off by it. So unfortunately it is not something that can be displayed meaningfully in visible light.
But, maybe you could find a different flaw in the exposure control. If not, you'll just have to be really bright.
