At present, 16-bit auto-scaled format results in incorrect alpha

Does that mean that there is an unreported bug in the colour

Forcing a manual conversion to the same output format as the auto-scaler avoids the error, so looks like a config error rather than the conversion itself

I don't have time to trace it at present. Only wanted to get the immediate use-case fixed.
