There seems to be a fair bit of bloating on some of the stars. I did an hour or so on M42 in UV and there are some halos and internal reflections on the brightest blue star in the field to the right of the main nebula. I've also noticed some stars almost invisible in IR flaring like a light house in UV and vice versa. I guess we don't notice that doing RGB because the Lum filters are already UV/IR cut. As you pointed out all you see in those pics is outside of the usual RGB space we image in, including narrow band emission lines.
