No, poor antialiasing makes the glyph look bolder. Specifically, drawing the antialiased text without taking into account screen gamma causes that.

You’d expect it to be, but not everywhere. The filter sum is ~1.4 or so with many libraries. This is to offset the gamma problem I mentioned above. I think skia’s renderer now actually does have sub-pixel gamma correction, and is properly normalized.
