Yes, it is a choice of placement in the response curb and it doesn't necessary affect contrast. But one will typically process differently to put it in more useful density range. So if one exposes D3200 at 400, then the processing is usually done much shorter, ie pulled processing - reducing contrast. In a practical sense, I think Polyglot is right although in purely technical sense, you are....

Either that... or strange things happen in down-under....
