[BUG] Modern UI applications icons

[fixer]

Modern UI applications were introduced in Windows 8. But while legacy applications usually have icons embedded into their files, Modern UI applications have separate folders where they keep their resources including icons. Sometimes there are icons of different size or different icons for different color schemes. The following official document descusses these icons https://docs.microsoft.com/en-us/windows/uwp/design/shell/tiles-and-notifications/app-assets#high-contrast-assets and it explains what different high-contrast schemes mean:

high-contrast white (white background with black text) and high-contrast black (black background with white text)

And if you take a look at default Modern UI applications shipped with Windows:
AlarmsStoreLogo.contrast-white_scale-200.png is indeed a black icon
StoreLogo.contrast-white_scale-100.png is also a black icon
CalculatorStoreLogo.contrast-white_scale-200.png is a white icon for some unknown reason.

And
AlarmsStoreLogo.contrast-black_scale-200.png is a white icon
StoreLogo.contrast-black_scale-100.png is also a white icon
CalculatorStoreLogo.contrast-black_scale-200.png is a black icon.

Not sure, whether this is a bug or a feature, but definitely doesn't look consistent to me.
