Unfortunately, it is true... but it does make sense.
If they filmed it in a larger/wider aspect ratio, then they'd have to "pan out" or shoot from farther away in order to fit the Hulk's height in the frame -- but then that would obviously make everyone else look even smaller.
Look at the bottom images (from Wikipedia). The top shot is in a smaller aspect ratio than the bottom; they are both shooting exactly the same width, but notice how the bottom, larger aspect ratio one cuts off the height. The top shot is in a smaller aspect ratio (like The Avengers). Notice how it fits the height better, but it looks "less cinematic" or more boxed-in:
