I would say that everything depends on the type of tournament, the number of participants, its stage. If it is a freeroll or a tournament with a large number of players, then showing a bluff is unlikely to give a long-term benefit, since you can always be transferred to another table. At a late stage with a large number of chips and with a good analysis of the opponent - it can have a very strong effect on them if you bluffed 1-2 times and at the same time won.
But in games like cash tables or spins, I don't think it will help, I would even say it will hurt more.
