I am fairly confident this advanced promo is also is a pre-master.
Disregard the below, it probably went through some normalisation process when ripped.

Yes, MP3 encoding can make things look less compressed but generally not this much.
One of the key things is that the average volume is 4dB lower, but it still peaks to -0dB, this is significant, as compression does not affect it quite this much.

In fact, decent comparisons can be made because the MP3 encoder version and settings are embedded in the MP3 itself.

By volume matching, and then re-encoding you can see the difference in the waveform clearly.

Here is the mastered version of A100 from the official release (red indicates clipping):


Here is the advanced promo:


Volume matching the official release to the advanced promo gives the following:


Encoding to MP3 with identical settings gives the following:


Overlaying the waveform of the newly encoded MP3 onto the advanced promo. The magenta is the waveform of the advanced copy:


And for good measure, the official release encoded to MP3 with no volume adjustments:
