Howdy.
It was, is, and never will be the primary job of the light source (bulb) to provide beam management. That is the primary function of the reflector or projector optics.
The two components are designed holistically, each having a specific function. The emitter to provide a consistent, accurately positioned, light source, and the reflector/projector to 'shape' that source into an effective pattern (distance, width, uniform distribution, 'cutoff' and intensity) downrange.
LEDs currently have a problem simply due to their design constraints - - the heat pipe prohibits the globular distribution of light as provided by a simple incandescent filament or HID plasma arc. The smaller/thinner the heat pipe gets, the less obtrusive it becomes. Not there yet.
Hece, we have a compromise - the 'active' LED emitter that is illuminating the correct portion of the reflector/projector bowl helps achieve the desired beam pattern/cutoff - but it's not by design, it's by coincidence. This is assuming that it's 3D-positioned accurately at the design location for the specific reflector/projector in the first place, and has at least a passing resemblance to the dispersion characteristics of the originally designed-for emitter - sadly, none of them really are.
Mori appears to be purty good in this regard all things considered, given the current constraints.
Oh - colour match (kelvin fer kelvin) - that'a a function of different CRI attributes between HID and LED.

No other bulb uses or has need for such - that is what the locking tabs on the base ( and corresponding slots on the housing ) are for - to precisely position the bulb. ( POS PNP HIDs excepted... lol). Positioning that requires fractional millimeter accuracy... and yer gunna eyeball it? Nupe.
I'm 110% positive that this is a marketing ploy to disguise ****-poor engineering. And they spin it to look like a 'positive' feature. Much worse - the vendors KNOW this, but happily lie to yer face while they take yer money.
Oh - those screenshots? That looks terrible, lol - no width, 'fuzzy pattern... looks like bad HID actually. Sorry. And also note that 'guygene' - aka elkhart, ,02_lightning, and all of his many other troll aliases he's use on this site, does not even have a 2016, nor even an EB. No pics in his 'intro post, no pics now. Ignore, Avoid this walking turd.
4X4 - you appear to have this same trolling turd stuck to yer ayss yet again. When are you going to do something about it - or do you actually prefer to be associated with trolls?

Sharp cutoff vs fuzzy cutoff, I'm not sure that it matters. The reason that euro lights have a sharp cut off is because signs are illuminated in Europe but not all are illuminated in the US. That sharp cutoff doesn't shine any light high enough to illuminate high signs. DOT spec headlight reflectors don't have a sharp cutoff.
