Label-as-curator is definitely a thing until the label gets too big. There were a few times in the nineties and noughties where I bought a sampler CD from a label because it had a track by an act I liked, and it would introduce me to other acts on that label who I went on to buy more stuff from. If a label owns subsidiary labels it is probably too big for this to work any more. If any of those subsidiary labels have multiple imprints of their own then it's definitely too big for this to mean anything, "Warner Brothers released this" tells you next to nothing about what to expect.
