The real problem is the directional adjustments of the light and the lenses

High power lights have existed for decades, but before LEDs they were prohibitevily expensive, so they were mostly used on semi trucks and other professional vehicles with more regulation on how those lights can be directed

I imagine most of the OEM lights are just as bright as most of the aftermarket stuff, but they are properly adjusted so they don't blind the oncoming traffic and you don't notice them
