I could be wrong, but my impression is the publishers (or, for that matter, any other businesses or websites) don't have any
reliable way to measure e-book "leakage."
You can, to some extent, track the web-wide distribution of a particular file... but if the file is altered or renamed, said tracking falls through. So it falls to polls of sample populations and a lot of guesswork, or embedded data that either self-reports to a server, or that coaxes users to click a link that tracks responses, to estimate distribution or leakage.
I don't even think e-book publishers are keeping track of erroneous or illicit DRM-release requests, much less embedding file-tracking bots or links into e-books.
