Yes. OpenType CEF fonts are now stem-darkening and rendered gamma-corrected, 
similarly to what CoreText would do. The result should be almost imperceptible 
with black on white, but produce sharper text with white on black that now has 
the same boldness as black on white has.

Unless something in Mac/freetype custom configuration interferes that is.
