Wow!
Thank you. Just in case you, or anyone else, would be interested in how this is done, I’ve just found free film grain overlays from shutterstock and dropped them above the timeline in Premiere Pro. You have to set the opacity to Overlay, but then you can do whatever color grading (I stick mostly to temperature and tint changes, as well as exposure, and some other stuff for individual shots). Its good because it doesn’t wash out colors, in fact it does the opposite in some cases.
