The huge Windows flaw is that it isn't color managed by default. It means that colors in most applications look extra saturated on wide gamut displays. I wonder if it the same flaw applies to HDR.. apps would look extra bright.

Macs and its apps have been properly color managed for decades. That's why the transition from SDR to HDR monitors has been painless. Apps have been ready for it for a long time.

No, apps on Windows HDR look normal unless they are HDR-aware and use the "extra brightness".

Windows apps don't even look correct on an SDR display!

I have a wide-gamut display and I can notice the difference between applications that incorrectly "stretch" sRGB to the display gamut versus apps that actually colour manage and map the colours correctly.

No app on Windows colour manages the UI widgets such as the icons, toolbars, etc... This is because the WDDM shell doesn't do any kind of colour management, it leaves that up to the application developers.

The sad thing is that Vista introduced an extremely wide scRGB gamut and WDDM had a number of internal features built around it. Unfortunately, it was only ever enabled for full-screen games, video overlays, and for internal use by apps that do colour management. They should have converted the entire desktop manager to use it.
