If no, you should be good; if yes, you're not.
Development by inspection is not done with the light on. The film is developed in total darkness for roughly 75-80% of the expected total development time, then a very dim safelight is turned on briefly to check the high values. Plus, most folks who do DBI use staining type developers which hardens the emulsion as the film is developed, thereby enabling the film to somewhat resist exposure to light.
