It would appear that there is still the possibility that Affinity Photo can have issues with the color/gamut when developing certain RAW files. I know this was a big issue addressed in the v1.5 update as referenced here, but it would appear that there is still work that could be done to improve this behavior. In all of the test photos, only Fuji RAW File Converter 3.x (SilkyPix 8.x engine) correctly rendered the color of the subject (ring) and didn't clip the colors. RawTherapee, DarkTable,
