The Byakugan allowed Neji to perfectly read Hinata and Naruto's body language for the most part, so it clearly has the power to read/react to small movements, not to mention Kidomaru's Spider War Bow wasn't exactly slow and it didn't stop Neji from reacting to it. On top of this, the sheer range of the Byakugan far outweighs the downsides, as being able to see someone at a distance, even through motion blur would save some trouble.

But I feel that this is getting somewhat off point since we know that Boruto's dojutsu isn't the Byakugan and the full extent of its abilities aren't yet known. We know it allows him to 'see' the negative chakra of Nue, so it might allow him to see targets like that without suffering the tunnel vision, but it is too early to tell.
