I don't really know how to test that.
Running weston-info, I get this:

subpixel_orientation: horizontal rgb, output_transform: normal

I don't know if this means subpixel stuff is in use, or merely that the hw 
supports it. I tried subpixel aliasing with X11 once - and no matter how I set 
it up, I got color artifacts. Haven't tried again, so it is not configured 
unless it is default in sway/wayland.

I tried magnifying a screendump containing a LyX window. There were clearly 
antialiasing, but no color artifacts in any windows (LyX, firefox and a 
terminal) The inactive window titlebar had some colorful effects - possibly 
subpixel aliasing. This was the only place I saw it.

I can test more, but then I need a guide on how to activate/set up subpixel 
rendering.
