Certain courts are most definitely tougher than others. The technology is there to do the lighting well, but this is often a case of building codes getting in the way. The last decade has seen many municipalities adopt "dark sky ordinances" that basically require lighting to be "full cutoff". Essentially what that means is that no lighting is cast upwards of the 90 degree plane above the fixture.
While this is generally a great concept (who needs light spill from parking lots for example) it is poorly apllied to court lighting. With no uplighting, the ball disappears against the sky the moment it is higher than the lamp. The other negative effect is that lighting tends to pool below the fixture and results in spotty, uneven distribution at eye level.
Some of the older courts around here have lights angled at 45 degrees. While the lights are older, they actually work better.
