If it was done properly, no. Though you can check if you can the Luma3ds menu shows up when holding start on boot.Is it possible to tell if a 3DS had CFW installed and then uninstalled? Wondering specifically about Luma3DS + boot9strap. Thanks in advance
Also check if the DS functionality works, DS connection settings etc. If they work, and if the system runs fine too, then you have nothing to worry about..
