Sometimes I might want to add a bit to get the album peak closer to 0dBFS, other times if I know the album average loudness is "hot" with many tracks already close to 0dBFS, I might add a small attenuation to give some overhead for the DSP.

Looking at truncation effects and playing with the settings, indeed, I can find that raising the dithering settings slightly to "Normal" dithering amount (with "Light" noise shaping to lower the <15kHz noise floor more) looks really good and might be my "standard" method.
