Why are the rounded edges for eg.: on MacBook Neo defined as small distance specs instead of a radius?

Because they're not circular arcs with a constant radius. They're "squircles". Apple uses those all over the place.

In my opinion it only makes sense for reflective surfaces (e.g. cars) to have nicely flowing reflections, while most of Apple's products have a matte finish. In 2D UI elements it most definitely makes no sense. But some designer must have been a big fan of this and somehow they now use it everywhere.

isn't the correct term Superellipse

According to [0], for icons at least, "no, not quite", because "Apple's exact icon outline is not a pure superellipse — it is built from carefully tuned Bézier curves that closely approximate one."

I can only guess, but I guess it IS because those are not circles but squircles maybe?
