And the degree of 3D with that effect is minimal at best, not a replacement for interaxial space, which is why it's only been used for macro that I know of.

Watch the video above about the Lytro CINEMA (not their PHOTOGRAPHY) camera at about the 8:00 minute mark. You can see with a (appropriate) lightfield camera like that you can, of course, get TRUE (as in 100% what we are talking about) stereoscopic image of ANY interaxial you want (within the constrain of the width of the sensor) which in this case is up to some 10cm (that camera has a up-to 104mm interaxial equivalence), so you can get the FULL range of interaxial used typically in current 3D stereocopic cinema.
So this camera can produce a TRUE stereocopic image of NOT ONLY the usual 6.5cm interaxial, but ANYTHING IN BETWEEN AND ABOVE (macro and hyper stereo, i.e.) and does it "at the same time", thus you get the multiview-equivalent of basically infinite-view (you see objects in different places in space with each eye as you move horizontally, like in real life, up to the width of the sensor/sensor-array) AND as a "plus" you also get infinite-focus (you see ANYTHING you want in focus, far or near by just refocusing your eyes, like in real life).
The problem I think is that you are talking about the Lytro PHOTOGRAPHY CAMERA and then viewing it in a 2D monitor or even a conventional 3D TV, which of course as you say is pretty useless for the glasses-free 3D display of movies that we are discussing here, and at best could be used to produce a small-interaxial multi-scopic image, like you mention, while we are talking about the Lytro CINEMA CAMERA and then viewed in a LIGHTFIELD DISPLAY, not a regular 2D/3D monitor like they are showing in the youtube video explanation, i.e.
A lightfield camera with all the (huge amount of) information being sent to a matching lightfield display is, intrinsically, true-3D and true-focus, as in real life, within the constrains of the size and resolution of the "sensor/sensor array" of the camera and the size and resolution of the LIGHTFIELD display.
