Yes that's not obvious but internally SRS in GDAL are not modelled as a
proj.4 string, but as WKT. So there's a importFromProj4() and
exportFromProj4(), and >possible loss can happen when some concepts
cannot be matched exactly.
Found these two that not even with the +wktext agree

OK, understood thanks. But got confused too. Why would a GDAL port of a
proj.4 string do a different thing than the coded in the proj.4 string?

gdaltransform -s_srs EPSG:4326 -t_srs "+proj=aeqd +ellps=WGS84 +units=m
+wktext"

And also found some that do no agree between GDAL and proj. For

echo 4.897 52.371 | proj +proj=vandg +ellps=WGS84 +units=m
