The difference between street and track use is simple,
Most people use silicone based fluid on the street which are not UV sensitive, hygroscopic, caustic, or needs to be changed...ever. No need to cover.
On the track most people use glycol based fluid because of it's better performance characteristics- better feel. Because glycol based fluids are very light sensitive they cover the reservoirs. Also because glycol fluids are hygroscopic, they have to be changed every year or two.
I use silicone based because I don't feel like fucking with it every year. I cover it because I like the way it looks.

You got that backwards. Silicon is for track use. Higher boiling point, but less stable and more expensive. DOT 3/4/5.1 brake fluids are glycol based. DOT 5 is silicon based, which is why they can't be mixed. You can bet mfgs will use the cheapest stuff they can find for production bikes. Glycol is the reason a lot of track orgs require you change coolant at higher levels.
I don't need no stinking sock. My reservoir is black with only a small window to check level.
