I understand the notion of wanting to see the movie as it looked on film, but keep in mind that Spirited Away was shot digitally. I think it was the first Ghibli film to do so. So as far as intended experience, the commercial blu ray probably comes pretty close. Color timing is handled respectfully. There’s no film grain that’s being managed or suppressed, so the only detail that could potentially be lost is in compression. The commercial blu ray looks really fantastic imo, so even as an avid fan of film prints, I don’t feel as though I’m really missing out. Ghibli treats it film catalog really well when it comes to home video release. Not at all like Disney’s revisionist methods.
