For those still wondering about how "correct" the 3D version of JP is, I have some info:
When doing a 3D conversion like this, not only do they have to "cut out" every element from each frame that they want to appear as 3D, it also adds problems with transparent or half-transparent (not sure if this is the right word for it) objects. This is very visible if comparing the two, and is also a reason why it isn't faithful to the original.
If I remember correct, the first trailer for the 3D version lacked the heavy DNR (but clearly showed the grain removal filter they used) but didn't have the green/orange tint the 3D blu-ray has. That was kinda their best effort at a good choice of color, until they edited it for the blu-ray which is plain horrible.
As for the placement of objects and generation of stuff that isn't even in the original frames, just look at the comparisons on caps-a-holic.
First one - Here they have separated the two men in the foreground as well as the plant on the bottom left from the background. Just look at the man on the left and how he's "zoomed in" in the 3D version. You can also see how the 3D version has added small extra half-transparent patches to the plant to cover up how it was cut out.
Second one - Here the whole gate has been cut out and you can clearly see how its shape is different in the 3D version.
Third one - One of the most horrible shots I've ever seen when it comes to 3D conversion. You can see it everywhere, look at the grass and plants in the background, foreground and on the sides. Look at Sam Neill's right foot, look at the grass straw at the left side of his left foot. It's all over the shot and it's so ugly and horrible.
Fourth one - Compare the tree on the rightmost edge.
Fifth one - Plants in the left side background and stone pillar in the right side foreground.
Sixth one - Missing hair behind his ear and on the left side overall. Very common result of cutting out an element with parts that are half-transparent.
Seventh one - To be honest I have no idea what they've done here. It looks like they wanted to separate his glasses, eyes and nose to make all look more 3D. In the 3D version his nostrils look bigger, moustache is blurred, eye larger...
Bottom line: 3D conversions like this are something to stay away from. The original is beautiful, the "3D version" is an ugly mess.
