sen2cor configurations

Hello all, I am wondering, if Sentinel-2 L2A data uses the same configuration in the sen2cor processor, independent from where it has been downloaded.
I asked the CODE-DE support team, and they informed me, that the use default or automatic settings, with a DEM correction and ESAs CCI sen2cor optimized LC product.
I asked the OpenHub support team and they said I should ask here.

Does anyone know, how the sen2cor configurations are, when downloading L2A data from the OpenHub?
Or do all L2A products use the same settings?

Thank you!
