Increasing scanline darkness SHOULD darken the screen, as the effect that your doing is increasing the spacing between raster lines. This darkens the picture. E.g. when I switch my Dell monitor to VGA mode the screen gets a bit darker, and the scanlines become visible. If the screen is too dark try increasing the backlight, or reduce shadow mask darkness.

As for white and black, well scanlines should be thinner for brighter colors as the color will bleed a bit.

Here are my aperture grille settings (which I use for TV games). I do not believe any arcade monitors have aperture grilles. Aperture grille was patented by Sony and only used for their TVs and some monitor brands they licensed the technology out to. However there is no reason why you could not just plug a trinitron into an arcade cabinet, so what you are doing here is certainly possible.
