There is actually a definition of what is correct, and I'm pretty sure Adobe Photoshop does it in one of its modes.

It's just pure grayscale antialiasing of the underlying letterform, with the correct gamma used by the monitor. Or subpixel rendering if you want, as long as it matches your screen's actual LCD layout.

The issue is that that's not necessarily what's most readable. So various forms of hinting and darkening can be introduced to improve readability, and all of that is of course entirely subjective.

Since readability is the most important factor in the area of text design, your definition of correct that goes against that is incorrect
