You aren't. Its just narrower and talle,r which may seem like one is to some iPhone plus adjusted users.I mean, practically the same amount of information is being displayed (the X has less text at the bottom, but that's because it has more text at the top from a caption, if it was scrolled down you would see the same amount of text in this article as on the Plus). It's just a different aspect ratio. I know it won't always be the case, but from this example, it seems we're not losing any screen real estate going from the Plus to the X.
