Can anyone clarify whether there is a real discrepancy between the
longitude (nadir) where I thought NOAA was declaring G16 operational,
which was 75.2 degrees (west) and the value found in the actual netCDF
files that states 75.0 degrees?
I can confirm the netcdf for you

As far is if it's actually where it's supposed to be
