Personally, I think the Dutch book industry would be shocked to see how many e-books they are NOT selling: all English e-books that are either not available in Dutch stores, or are over-the-top expensive compared to almost any store in an English-speaking country you care to buy in.

Everybody I know who has an e-reader reads English books exclusively, and buys them anywhere apart from the Netherlands. My sole exception is one of my aunts, as she doesn't know English.

So yes, the sales of e-books in Dutch may be low, and the sales in Dutch e-book stores may be low too, but I would not be surprised if e-books have a MUCH bigger market share than expected if English books and books not bought in The Netherlands would be counted as well; but that's very hard to check, obviously.
