Please ignore this query. It turns out the new version of NASA OCSSW software
is the issue. It has multiple values near -32768 that is no data. I cleaned up
the file with gdal_calc and things seem to be working ok now.

Michael,
I'm not totally sure if image composition really belongs to gdaldem. It
feels it is more generic than that, although making nice looking DEM
rendering is definitely a common use case. There's this long existing
Python script at
