Film grain looks good until you hit a resolution (and color detail) that consistently exceeds the perceived boost that grain provides... which barely exists in pixelated screens in the first place. It provides some anti-aliasing and moire-reduction (at the cost of fuzziness), but that's about it. When those smooth-then-pixelated-then-smooth lines transition to even-smoother, like 4K / HDR consistently hits, grain looks like the muddying noise that it really is.
