I kind of doubt they make the exact same film stock as was used in the 70’s. That film stock caused no end of preservation headaches for many a film shot in that decade to begin with.
Digital Intermediates have been the industry standard for quite some time. I don’t think anybody does it the old way anymore, if the ability to do so even exists at all. Might as well carp that they didn’t edit the film by physically splicing it together.
