The electric E-Fan training aircraft is a highly innovative technology experimental demonstrator based on an all-composite construction. Airbus Group and its partners are aiming to perform research and development to construct a series version of the E-Fan and propose an industrial plan for a production facility close to Bordeaux Airport

Such belly markings are typically used for branding in air show flyby.
A flying debut is the signature moment in the development of any new plane, when the industry goes into publicity overdrive. A 600km trip from Toulouse to Le Bourget is surely the unannounced-target of Airbus; date of first flight is not certain, and those of the following flights are even more uncertain as you will never know what issues have to be resolved. So, if one of the test flights can be combined with a flyby at Le Bourget it would be a bonus, but not a priority.
