It depends. If you play someone of similar strength, just as you might not know how to punish every inaccuracy your opponent will not put up the most stubborn defence. Understanding the opening will be an advantage, not a disadvantage.
How much of your study time you should allocate to openings is another question entirely and depends on your level and what you are struggling with. If you play e3-Ke2-Ke1 against everything you might want to revise that opening repertoire before you play the next GM-norm tournament.
That being said, openings are usually getting more attention than they deserve, but knowing them is not useless and understanding them is even better.
