I think this is a known limitation of baked probes, see https://docs.blender.org/manual/en/dev/render/eevee/limitations.html#indirect-lighting

Eevee does not support “specular to diffuse” light bounces nor “specular to specular” light bounces. All specular lighting is turned off during baking.

For specular-specular you need to use SSR.

Will archive this report (unless @Clément Foucault (fclem) has anything to add?)

You can make the object appear diffuse in the reflections if you want, by using the light path node and a mix shader.
