Analog de-emph is what happens in your CD player as you are listening. There's a de-emp circuit that applies a custom EQ curve to make it sound the way it is supposed to by pulling the treble down with a specific curve.
Digital de-emp is taking the WAV file and manipulating the EQ and creating a new digital file that hopefully replicates what an accurate analog de-emph is supposed to sound like.
If what you are hearing has way too much treble and sounds way too bright and brittle then you are not hearing it de-emph'd. You are hearing that treble emphasis.
If what you are hearing sounds good then you are OK.
The whole point of emphasis/de-emphasis was to provide something similar to Dolby noise reduction but it was to reduce the noise supposedly created by early A/D and D/A conversion (I think). This process is no longer used.
