Ae defaults to blending in a gamma-encoded space, but Pr defaults to blending in a linear space (when GPU acceleration is on). This probably accounts for the difference in compositing that you’re seeing. To fix this, you can either change Ae to match Premiere, or change Premiere to match Ae.
To change Ae, open your project preferences and either set the working space to a linear space, or check the “Blend colors using 1.0 gamma” box.
To change Pr, open your sequence settings and uncheck “Composite in linear color (requires GPU acceleration or max render quality)”.
