The 2.20:1 aspect ratio is not zoomed/cropped but open matte. Titanic was shot 98 percent on Super35 film (underwater shots of the wreckage were techniscope), which gives an image slightly wider than 1.33:1. About 16:10 perhaps. The 2.20:1 aspect ratio was used on the film’s 5-perf 70mm theatrical release back in the day. In the 70mm the film had more image vertically while not losing anything from the sides.
I have also seen this HDTV broadcast (which is actually more of 2.25:1) and it is both taller and wider than both the 2D and 3D Blu-ray.

In this case it is zoomed. Here’s the same shot from the uncropped 720p ORF1 HD-broadcast which used the same master (somehow Imgur is just not working for me, so I had to use another site):

There’s slightly more information on the left and right side compared to the ProSiebenSAT.1-broadcasts. It’s not much, but the zoom is definitely there. But you’re right, it shows a little bit more than the 2012-version:

@JayArgonaut: Thanks - that was the information I was looking for. 😃
Funfact by the way: There was a rerun on Austrian TV this afternoon (2:30 - 6 pm). I checked one of those reruns on that channel back in 2013 and it was completely uncut. Seems like Austrian kids don’t get nightmares of “Titanic” like kids in other countries might. 😉
