It makes sense they would be the same or very similar in that Galerie was a graded paper - ie little need for dye sensitization other than to increase overall speed to incandescent light sources (which would be needed for a pure chloride emulsion but not the mixed chlorobromide or bromide emulsions of enlarging papers). The graph does more or less line up with the spectral sensitivity of a non-dye sensitized, mixed halide emulsion (see Haist, James etc.) or what we tend to refer to as “blue sensitive”.

You can find similar curves in tech docs for various bygone graded enlarging papers like Brovira etc.
