I don't think the nudity is any less gratuitous than, say, GoT. It's actually more warranted here as not only are they dealing with hyper-realistic androids but they want to show to what extent man is capable of physical or sexual violence when there is no culpability. Apparently there is no limit. But then again is the violence really that abhorrent when you know it is only a synthetic being that you are either shooting or shagging, and they were created specifically for that purpose.
