I have no specific knowledge of badminton, but let's say a skilled player can hit the "ball" at 100 km/h. That is 28 m/s.
In both cases that speed is peanuts when compared to the speed of light for both Sindu and Bindu. There would be no difference in the gameplay of the two.
Furthermore, signal processing in our brain takes about milliseconds, which is way more than the time photons need to go from the "viewed object" to the "viewer" on a badminton court. Again, no appreciable difference.
