Maybe, maybe not. Rogers and Hammerstein? Gershwin and Gershwin? Lerner and Lowe?
The answers will say a lot about someone's familiarity with genres of music and their preferences and maybe less about composers and lyricists.
I think the composer's place in time makes a huge difference. The composers you mention did not "evolve" in their songwriting the way The Beatles did, but they also did not have the recording technology advancements along the way that The Beatles did. Along with recording technology, the cultural shifts of the '60's absolutely played a role in the Beatles' work. If your point is that you can't compare eras ("genres"), I agree.
