In a sense, if the resolution is high enough. One notable limitation of the angular-pixel approach is that the angular resolution of the pixel becomes diffraction-limited as the pixel size shrinks - the puts you between a rock and a hard place with the twin goals of "small enough pixels that you can't see them" and "enough viewing angles that you can't perceive the steps", even if you had a hypothetical umpteen-zillion gigapixel display. "True" holograms are coherent across their entire surface, so they don't have this limitation. This isn't even close, though. Horizontal parallax only and only a few dozen angles (over a wide FOV!) puts it more in the territory of lenticulars than true lightfield displays. To be fair that is enough to achieve a 'wow factor', and a true lightfield display is a Hard Problem (that Fovi3d are trying to solve, if you're interested in the state of the art).
