Yep, there would be scene lights set up there. Not sure if Corona would have access to the "magical not really there" lights used in the viewport, since it doesn't in Max, that may be for good reasons (even for keeping functionality the same across different apps, I guess if it was to be added in C4D it would have to show up in Max too, so that Corona works the same and is familiar whichever version of it you choose to use, meaning you'd have to convince the core team that there was good reason to have this ;) )
