I created some screenshots to compare (around 13 January 2018):
browser_freetype2_2.8_lcd_filtering_off.png - with LCD_FILTERING=off for
freetype2 v2.8
browser_freetype2_2.8_lcd_filtering_on.png - with LCD_FILTERING=on for
freetype2 v2.8
browser_freetype2_2.9_lcd_filtering_off_(harmony).png - with LCD_FILTERING=off
for freetype2 v2.9
browser_freetype2_2.9_lcd_filtering_on.png - with LCD_FILTERING=on for
freetype2 v2.9

For following comparisons:
- Differences between grey colour rendering (LCD_FILTERING=off) and subpixel
rendering (LCD_FILTERING=on) for freetype2 v2.8:
% compare browser_freetype2_2.8_lcd_filtering_off.png
browser_freetype2_2.8_lcd_filtering_on.png comparison/2.8_off-2.8_on.png

- Almost identical images between freetype2 v2.8 and v2.9, when subpixel
rendering was enabled (LCD_FILTERING=on):
% compare browser_freetype2_2.8_lcd_filtering_on.png
browser_freetype2_2.9_lcd_filtering_on.png comparison/2.8_on-2.9_on.png

- Differences between "harmony LCD rendering" (LCD_FILTERING=off) and subpixel
rendering (LCD_FILTERING=on) for freetype2 v2.9:
% compare browser_freetype2_2.9_lcd_filtering_off_\(harmony\).png
browser_freetype2_2.9_lcd_filtering_on.png comparison/2.9_off-2.9_on.png

Other port's options were:
DEBUG=off, DOCS=on, LONG_PCF_NAMES=on, PNG=on, TABLE_VALIDATION=off, V38=off,
V40=off, FIX_SIZE_METRICS=on, TT_SIZE_METRICS=off.
