Hendrix and the Experience redefined rock and roll.

Sure, it started as amped up blues. It quickly moved to something else entirely.

And Kraftwerk redefined music 10 years later with the introduction of electronics in full replacement of instruments.

His early work in the UK was blues. Clean guitar sound, amazing ability.

When he flipped the dials to 11, hit the recording studio and began "the Experience" it was no longer blues, no longer the "british invasion", it was new, it was undeniable and it made the further migration of hard rock (Purple, Sabbath) acceptable. He turned the guitar into the driver of a bands sound instead of the jangly back up instrument to bass and drums.

You can hear the differences in approach pre and post Hendrix in dozens of bands and guitarists. Clapton, Pete Townsend, Jimmy Page, all show marked changes in their style and approach PH (post hendrix). He changed everything. Including what was considered Blues.

Floyd and the psychedelic were part of that, and Hendrix drew from that genre...but their impact later was influenced by Hendrix...and David Gilmore will tell you as much.
