The theatrical R-rated version and unrated version are different only in the second morgue scene as follows: (A) Female genital nudity is depicted 1 hour 29 minutes and 0 seconds into the film. In the R rated version (which played in US theaters), when Ruby was kissing the corpse (played by a female actress), the bottom of the frame showed the upper half of the vulva (inclusive of somewhat blurred labia, due to the camera focus on the kissing). In the "unrated" version (NOT the theatrical version or the director's narrative - which both emulate the R rated version seen in US theaters), that same moment depicts VERY clear labial exposure (as in medical clarity, yet artistically depicted). (B) Note that the unrated version also shows Ruby's hand brush along the genitalia as it sweeps up to the left breast (R rated version prolongs the cut-away to the Jessie fantasy shot), and also depicts Ruby bouncing on the corpse as she reaches orgasm (while the R rated version shows only the close up of her face). The foley work and soundtrack during the unrated morgue scene are subtly but noticeably different. In short, the unrated cut sounds a lot more "squishy" with ample "smacking" sounds. The uncut version appears to be available through iTunes only, despite being an Amazon production,which you can find here: https://itunes.apple.com/mt/movie/the-neon-demon/id1129719992 (That means if you want to watch it on a TV you'll need an AppleTV to play it).
