Yes, absolutely. This wasn't a very large gamma ray burst - as far as I know it may have not been followed up at all. GRBs are hard to localize - but the detection of the gravitational wave made it possible to search for the source quickly in a much smaller area of the sky. This got a lot of people looking, and a lot of good data collected.
