You're confusing equal temperament with monotonic.

Just because an instrument uses the same fingering for Eb and D# (on a
trumpet that would be first valve, I believe), doesn't mean that the
note is equal temperament, or an accurate Eb or D#. And it's a pretty
safe bet that if the player plays the two notes an octave apart they
almost certainly aren't an accurate octave ... an Eb, a D#, and the
equal temperament fudge are three distinct notes, and your trumpet is
probably playing a fourth. True, they're all ALMOST the same ... :-)
