I understand your rational. Most LED diodes usually face sideways. With reflector bowl, this theoretically may cause horizontal beam to be more intense. Therefore, the perceived blinding effect for oncoming traffic.
But the practical result still stands itself. When I first installed the LED lights, I only put on left side (both low beam and high beam), then I compared the beam patterns of both lo beam and high beam with those of OEM halogen bulbs on the right side, side by side. I do not see significant beam pattern changes (The light coverage area is NEITHER WIDER NOR TALLER). The cutoff of lo beam is clean. High beam throw pattern also very similar. Sure LEDs are brighter and whiter, beam patterns are still evenly lit, comparable to that of halogen bulbs in my case. Anyway this is just my data point, not necessarily representative for all LED bulbs retrofitting all halogen light housing.
Heat dissipation could be an issue. The LED bulb came with heat fan, which will probably fail first. Only time will tell.
Light bar is for off-road use only. I believe it is illegal for most public road anyway.
