Human eyes have higher spatial brightness resolution than spatial color resolution.
At the cost of software complexity and mild computation overhead, a screen like a Bayer matrix or technology-appropriate similar subpixel layouts together with software that properly anti-aliases content by clamping brightness and color resolution separately to appropriate values ensuring the screen will remain capable of showing the limit frequency and that the two limits are sufficiently close to not disturb the eyes/viewer, will result in better viewing than if you lazily forcibly clamp the brightness and color resolution to the same value as Apple did.
If you have a non-"default" screen subpixel layout then you need to remain able to drive each subpixel individually from the computer and to have the antialiasing algorithm be aware of the specific arrangement you have.
And no, until you can point me to a sub-2000$ (and at that price and that poor contrast, a minimum of 120 Hz) 35~55" screen with at least 2500:1 static contrast, a vaguely 16:9 aspect ratio (though I'll accept 4:3 with the same pixel count and density and accordingly scaled dimensions), and at least 10k individually addressed (and anti-aliased onto by the font rendering) horizontal pixels, I'll happily stay with my 11520 horizontal (sub-)pixels that I paid about 700$ for (43", 5000:1 static contrast, 60Hz).
