Research direction
Start by reproducing the issue in darktable's lighttable and darkroom using the attached IMG_3870.CR2.txt XMP file on Linux/FreeBSD 15.0 with darktable 5.4.1. Compare the image before and after entering darkroom; done means the old edited image displays without a purple tinge in either view.
