In PhotoLab 6, select the DxO Wide Gamut working color space. For Color Rendering, select Category: Color positive films / Rendering: Kodak EIR (DxO FilmPack) / Intensity 100. The image is rendered wrongly, in practically every color:
Now select the Classic/Legacy working color space. The image is rendered with reds turning yellow and other colors turning red:
Other film renderings seem to have some trouble, too. Lomography Redscale reddens only part of the image in PL6 with the WG WCS and the whole image with the Classic WCS. Fuji Sepia leaves greens intact with the WG WCS but turns the whole image sepia with the Classic WCS. The Pastel rendering is quite different with greens, too: with the WG WCS, greens are too saturated even with soft proofing showing them within the sRGB gamut.
