I regularly get books from NetGalley, both PDF and epub. They are mailed to my Fire tablet through the @kindle address, which I assume is Send To Kindle. They vary a lot in line spacing, and highlights do not show up at read.amazon.com/notebook as do books I borrow from the e-brary or (infrequently) purchase from Amazon.
But perhaps this is neither sideloading nor Send to Kindle? They don't have a cover image.
