There are several possible issues here:

  • All software has bugs. If you lose your original, the DNG may not have all the same data due to a bug in the converter.
  • Some raw converters treat originals and DNG files differently. So even if there is no bug, the results may come out different even if they have the exact same data and metadata.

It your DNG converter doesn't have any bugs, and your raw converter treats both files the exact same, then you will get the same results from the DNG as from the original.
