The azw3/kf8, or Calibre Dual Mobi (not Previewer) with Publisher selected on an actual Kindle (K3 or later, not DGX) is more similar to epub2 than KFX is to epub2 or epub3. Some epub3 works.
Oddly not all eink kindles do images identically, depending on how the image is specified. It's more subtle than the 3 resolutions of 167 dpi, <something more> and the 300 dpi on Voyage/Paperwhite3/Oasis1 and later. The Kindle Basic models used 167 dpi for some time after the Voyage/Paperwhite3/Oasis1 (first 300 dpi models).
