Apple and Microsoft have different approaches when it comes to their products. Apple has the advantage of controlling both the hardware and software, which allows for the creation of an integrated hardware-software system where both components work together with a high degree of interaction. This means they can fine-tune features like dithering in macOS using custom-developed drivers because they know exactly which hardware will be used.
On the other hand, Microsoft doesn't have the same level of control over the hardware since they work with various manufacturers. This makes it a bit trickier for them to offer such a high level of integration. They rely on graphics card makers to handle these specifics, which means they can't always ensure consistency across devices. Therefore, their capabilities in this matter will always be limited.
