I thought that they don’t necessarily aim for a guess at true color but instead for coloration that conveys the most detail. Again, would love to know if I’m wrong. Also I think the JWST images are not exactly “official” but open submission because everyone and anyone can not only access the data for processing into an image (outside of an exclusion window to allow people to write research papers) but also request where the telescope is pointed.
Edit: it probably depends. This being a planet, it might make sense to stick to true visible light coloring but nebula and galaxies might not matter as much
