If you examine the .lfp file, it shows that it stores a set of 1080x1080 JPEGs representing different images planes in the light field along with their depths. There is also a 25x25 look up table of the depth levels of the image, presumably to enable a UI in which the user clicks on a portion of the image and the nearest JPEG plane is displayed. Note that some of the older images in their gallery are at lower resolutions like 831x831.
This is just their fairly simple compressed format for web display. I imagine the camera itself is storing much more interesting information in its ~20 megabyte files, though perhaps also ultimately for 1080x1080 2D display.
