What is missing from this discussion is how uneven the tension was before you took it to the shop. They might have really messed up the wheel or they might have done the best possible job with a wheel that uneven NDS tension to begin with. cxwrench (and others) gave good advice: if the wheel is round and true, just ride it. Keep track of how well it holds its true because if it comes out of true quickly then the wheel job wasn't a good one. Uneven tension is indeed a source of spoke breakage, but since we have no idea how much variation there actually is, we can't make any predictions.
