The last time I delved into this (a few years ago), the answer was no, as far as AZW3 goes. This is roughly how it worked then (don't know if there have been any changes since):
E-ink Kindles get AZW3 covers by downloading the image directly from Amazon's server based on the ASIN number embedded in the ebook.
If you use Calibre to sideload via USB, Calibre will copy the image to the Kindle for you.
If you include the ASIN in the opf (
<dc:identifier>urn:mobi-asin:B000000000</dc:identifier> or
<dc:identifier>urn:amazon:B000000000</dc:identifier> ), you can use Calibre's Quality Check plugin to embed the ASIN ("Fix ASIN for Kindle Fire" command). You can also use the KindleGen plugin for Sigil to do this by checking the "Add Fake ASIN" box. Make sure you have WiFi on when you sideload the book and your Kindle will download the cover based on the embedded ASIN.
The problem with Send-to-Kindle is that when you send a dual-mobi (containing both AZW3/KF8 and old mobi formats), Amazon creates a new ASIN for the AZW3 and overwrites whatever ASIN you may have embedded yourself. As a result, eink Kindles that receive the AZW3 are not able to download the cover and you get a generic cover. (I don't know about Android, but iOS uses yet another format, AZK, which appears to use the cover image inside the ebook so don't have this problem.)
So for eink Kindles, if you prefer AZW3 format (as I do), you have to choose between Whispersync and covers.
