Composite noise should effect the image

[Degamisu]

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.
