The crux is the "later on" algorithmically combining data/datasets on
device is at least a grey area, specifically if the non-OSM data is
actually dynamic. As a tendency I would lean on the side of the result
being a produced work and that 4.5.b would apply. Naturally you can
create some undesirable corner cases (distributing a diff between OSM
and your OSM+), but that's probably unavoidable and likely not to have
any real consequences.

You are never required to publish you original proprietary data, just
the derivative database (if it actually exists).
