You can see different images of the Horsehead nebula and the differences in how colors are presented. They vary substantially, but not in any way that matters, at least to me on an aesthetic level. It's more like the difference between different white balances (which are, to some extent and in some contexts, arbitrary) in a terrestrial image.
Maybe one or another of them is more "true to life" but since human eyes never evolved to view this stuff, there's no reason to think that the best and most informative view of an astronomical object is the visible light one.
