I think the argument is that the valley is further left on unfamiliar scenes, as "can just barely tell it's wrong" is more wrong for those things that stuff we know really well.

Alternatively you could say "Orcs are unreal, so there isn't an uncanny valley at all for them"

The orcs were mostly CG, I think that has more to do with it. If they were people in makeup and masks, I suspect they still would have felt uncanny. In fact, the orcs in the large battlefield towards the beginning were mostly costumed, and felt uncanny, while the band of orcs later were CG, and felt OK.

True, in which case I think putting the orcs elevated out of the uncanny valley towards reality is probably a strange thing to do! Can't remember the last time I came across an orc on the way to the shops..! Same theory still applies for panning through scenery or walking thru a marketplace though.
