The mean of a binary variable (coded 0, 1) is the proportion of 1s, so
you don't need to anything special after a linear probability model to
get the interpretation in terms of differences in
probabilities/proportions. This is the whole point of using linear
probability models.

Hope this helps,
Maarten
