Isolating and looking at my power planes in KiCAD, they seem a bit more divided than I wished they were..

The clearance in the design rules is set to 0.2 mm, and the copper fill strangely gives way to via annular rings in other layers... Looking at the 3D Viewer it's more obvious what's going on:

The via pad stack has annular rings in layers where they are unused -- and the copper fill respects the clearance just as being told. Poking around on the internet revealed that other people had the same issue, however, only workarounds seem to be available at the moment... I'm not gonna dig too deep into KiCAD, so I will let this one rest for now.
