As for the G20, the images I find for RoW look like the image below. The US headlights have blue pieces there too. I was just curious how different those pieces are since the part numbers are different.
I am well aware of the legalities and why we don't have it, but I hold a small hope that maybe the blue light is like anti-dazzle and can be activated.

I just supplied the examples of two US vs Row vehicles which I was able to locate online to support my claim. A G20 compare and contrast wasn't available.
Anyone with a US-spec G20 with Laser Lights can confirm that it's white and those with a RoW can confirm that its a much more noticeable shade of blue. I assume that would self-explanatory.
BMW's laser headlights work is by aiming a trio of blue-laser diodes, situated at the rear of the light assembly, into a set of mirrors, which reverse the direction of the light and send it through a lens filled with yellow phosphorus, this is why the US-spec lights still have a slight blue hue within the diodes.
However, the yellow phosphorus responsible for the color shift is
physically skewed towards producing a white light output, in order to meet US regulations.
The yellow phosphorous lens It's not controlled by software, thus, it's not just a matter of simple coding to alternate the colors, there is a physical difference.
Aside from the main high-beam, the running lights itself is also physically white in US-spec vehicles and is not capable of color-shifting to blue.
The part numbers are different between both regions not only because of the difference in hue but also because all US-spec vehicles must have a DOT stamp indicating that they meet the all legal requirements and also a physical light level adjuster, the RoW doesn't need to have this requirement.
I hope you don't assume I'm trying to burst your bubble or anything because I also hope it was just a matter of coding to make them blue as the RoW but I'm merely pointing out that it's not physically possible in the BMW setup.
