This still shows the uncombined components. What does the color blue represent in this map? Is it a height? -500m? 5000m? 6000m? What does white represent? This map is a fundamental misrepresentation of the actual data.

This is the formula:

height = -10000 + ((R * 256 * 256 + G * 256 + B) * 0.1)

No it doesn't. I think you're misunderstanding the site. It deliberately uses a weird banded colour scale so you can see where height changes on a fine scale.

They didn't interpret the data wrong.
