Composite noise should effect the image
My latest preset, the Low Power TV preset needed some workarounds, using the edge wave to pretend that the composite noise affected how the image is represented. I turned off the edge wave to demonstrate the issue.
However when I lower the bandwidth, it looks like this.
The actual image is completely unaffected by the noise.
Coming back to this--I'm not sure what's not working here. Is it that the color information isn't affected with the bandwidth scale lowered and only the luminance is?

My original issue might be a little confusing, what I meant is that the luminance does not appear to be affected by the noise. I couldn't find much on this, but looking at image B, the luminance video is rather stable, making the noise look more like an overlay than a true artifact.
Since each grain is supposed to be embedded into the video signal, it should affect the image. In the second photo, however, the luminance is completely unaffected.
