Nope, at least not yet/not for historic data.

As windows build includes all languages, and windows users are by
magnitude the biggest part of users (and most linux users very likely
use their distro's version), there's no way to distinguish between
what languages are actually used.

info in an update ping is the based on the UpdateUserAgent string
that's taken from versionrc/version.ini and looks like this for
example:

LibreOffice 4.1.0.4

→ Version used (human readable)

 (89ea49ddacd9aa532507cbf852f2bb22b1ace28;

→ the commit hash the build was based on

 Windows; x86;

→ OS and architecture/variant

→ List of languages, in the case of Windows build → all (doesn't
distinguish between actually installed languages/languages in the
installer)

The BundledLanguages parameter is actually pretty useless in this regard.

However the request is also sent with a HTTP_ACCEPT_LANGUAGE header
that corresponds to the UI-language, but that's not logged anywhere,
so cannot create data from that right now (would be possible to add in
future though)
http://opengrok.libreoffice.org/xref/core/extensions/source/update/feed/updatefeed.cxx#359

The only approximation we have in regards to what languages are used
are the download numbers for the helppacks on windows and/or the
languagepacks on Mac/Linux - but helppacks are often not downloaded at
all (either because not available for a language, or because people
just use wikihelp instead), and Mac/Linux has too few market share
compared to windows to be a trustworthy indicator.

So only part we can do is to use geolocation of the requesting IP to
see where in the world LO is used (and has update-check enabled) - but
not in what language the UI is used.

So using the update-check pings, we could evaluate the Accept-language
header to create ratios (but of course no absolute numbers, as there
are no unique IDs and one client pings multiple times, and the
poll-ratio also is configurable) that probably would satisfy the
request.

i.e. it would be possible to create in future reports for
* geolocation
* UI-locale from request-header

but not
* list of actually installed locales
for that the BundledLanguages parameter would need to change or
additional one would have to be introduced.
