You would indeed be wrong - they're exclusive alright, but mostly KonamiStyle exclusives, not Dengeki.
Most of the actual Dengeki exclusives are quite old now - the opposite-colour original Arnval/Strarf repaints (and repeated with Bis/Tranche 2), the black Eukrante and Ianeira repaints (which I think were announced for a reissue at the same time as regular Eukrante), and I think the opposite-colour Valona/Werkstra repaints were Dengeki-exclusive too. Not sure they've had any recently, other than the aforementioned reissues of the Eukrante/Ianeira repaints.
They seem to be including more new parts with repaints in general these days; presumably because it leads to more sales (possibly spurred by the success of Tempesta/Lavina? I think that was the first time a repaint of any set had come with quite that many new parts).
Eukrante being a reissue though, just included the new parts that were originally created for the Dengeki repaint back in the day (and even used the old-style box, rather than the new one that any modern release, and even repaints like the Bragg/Zel repaints used)
