Reduced noise in dust.....don't know what else to do, other than piling on the data

Are you creating a synthetic L from all that RGB data in the LRGB version? Given how much you collected, it may strengthen the L data.

Is something going on at the edges of the image? I'm not sure if its real or an artefact but the border looks distinctly different to the main image.

I tried the superluminance route--in the end the straight luminance proved better.  The right hand edge is devoid of dust--so space is clearly seen.  I have removed a magenta cast from that area--maybe I missed some.
