What is the content of the elevation map geotiff produced by Autodesk Forge's Reality Capture API?

Question

I am looking for information which describes the elevation map geotiff produced by Autodesk Forge's Reality Capture (Recap) API. Is this a colorized "heatmap" or is this a matrix of elevation values in meters, feet, etc?

I read through the documentation provided by Autodesk, but it did not specify, nor provide an example. I also searched online, including Stackoverflow, and found no mention of it in other questions.

GeoTIFF is a standard format that can be read by many (GIS) applications.

It actually encodes the elevation values, and the colorized heat map is just one way of rendering/representing it.

For example one can load it with the tifffile module in Python and it renders like below with the colors of the map customizable:
