Normal LED headlights and output

Does anyone know if the normal LED headlight is restricted and has lower output without the headlight wash system option added?
Currently I have an A3 8V with Xenon where the wash system is included and I really like the light output of that system. I have now opted for an A4 with normal LED but haven't really given any thoughts to if the wash system could make a difference.

i previously had a 2016 A6 with standard leds and washers. i now have a A4B9 with standard leds without washers and they are just as bright as my A6 were. much brighter than my 2009 mondeo with HIDs ever were.

I’ve driven my S4 with the matrix LED setup (which has the washers) and an S4 with normal LED headlights (without the washers) and I couldn’t tell an ounce of difference in the output so I wouldn’t worry about it.

They’re better than my B8.5 xenons were as well.

The design rules required headlamp washers and auto levelling if output of dipped lights was over 2000 lumens as this link explains.

The standard LED must be under 2000 lumens but probably the better optics of the LED lamps means that the real world difference is negligible, I certainly don't think my standard LED lights are less bright than the Xenons in my previous car. I'm guessing that due to the auto high beam shaping aspect of the Matrix headlights they must put out over 2000 lumens in that mode but are probably the same as standard in normal dipped beam mode.

Could be. Or might be so they’re as clean as possible to stop any light scatter since they need to be fairly accurate as they turn segments on and off?
