It isn't quite false advertising.
I will attribute it to an omission based on the needs of the many rather than on the needs of the few.

Rarely do I have the need to bring a 'raster' (ie *.tif) back in to ArcGIS PRO or ArcMap. I did and discovered, that arcpy.RasterToNumPyArray seems to only like bringing back a limited amount of data, probably with the expectation that user wants to map floating point values (ie 1 band) or integer values ( ie 3 bands for a 'picture'/'map').
This is a work-around, built-in.
You can of course store anything numeric in a tiff. How about some statistics for our array 'a'.

There are a number of options within the Esri suite of software, some of it relies in part on open source offerings. Some of these (ie libtiff and tifffile) have even made it into open source software too (ie GDAL, scipy.ndimage and skimage etc etc), kindof like open source-open source.
Enough for now.
