But at the end, L is not a channel in an RGB image. R, G, and B are. L is used to enhance an image with weak RGB channels, because we perceive resolution in the luminance of an image, but no so much in the chrominance. But if the goal is to have the best color accuracy, then it seems better to capture correctly exposed RGB channels, and then there's no reason to capture L, right? The luminance of the image will be good, if the color channels are good. Probably add Ha capture, if the red filter cuts this important line.

I find that without adding Luminance to my pictures that they lack "punch".
The colours look weak.
Also - maybe since there is a crossover between some colours on all of our so called RGB filters
that perhaps we're kidding ourselves that we're viewing the correct colours?
The processing of pictures becomes subjective & open to
artistic license & a general consensus seems to build up over time
as to what a target is supposed to look like.
We then process to get similar colours.
