You should perhaps then look into Page with the Yardbirds where any tangible influence from "the blues" (man) would perhaps be more obvious.
More or less every musician from the 60s could claim influence from the blues, Chuck Berry, JLL but then that was the music that immediately went before them. Not so easy then to identify any influence as their career progressed.
Lemmy from Motorhead, biggest influence on his career (other than drugs)? The Beatles.
Go figure.
