Antialiased lines of width 1 pixel do generally look a bit thicker than they should, when compared to non-AA lines. This is because exact pixel coverage is computed, and neighboring pixels are also affected a little bit. Some more in-depth explanations can be found here:

However, a different gamma would be necessary for dark vs. light background colors, so it would not be a universal solution.
