Subpixel antialising is disabled by default on Apple retina (everyone else calls it HiDPI) and is only needed ever on lower resolution displays.

That is NOT sub=pixel addressing. The Cleartype and similar on non=MS only works on a three colour stripe display. It only adds a pseudo increase in resolution across the stripes, but we benefit from increased horizontal resolution on fonts.

So displays with R G Y B or R G B G arrays can't use it. Nor does it work sensibly on CRTs. Only well on digitally connected external LCD/OLED, not VGA or Analog on DVI.

So-called "Retina" is simply Apple branding for higher DPI displays where at normal view distance you can't see the pixels.
By default on a smaller panel you use 2 x 2 for each logical pixel. With the same number of pixels on a twice as big panel the Retina mode (HiDPI for everyone else) needs turned off.
Cleartype and similar schemes are for RGB stripes where the R G & B pixels are 1/3rd width and DPI is less than about 133. At about 120 to 200 on a full colour display simply using regular anti-aliasing and no "sub-pixel" on the RGB is better. Higher display DPIs or longer viewing distance don't need any anti-aliasing or "sub-pixel" addressing.

All of this is easier to change on Windows and especially Linux than Apple MacOS which might insist on ignoring screen physical size and keeping "Retina mode" on.
