I don't think David Bowie was actually an invert. "He" was definitely a psyop, creating gender confusion, and I also think "he" is still alive but his gender is hard to pick.
Check out this photo of David Bowie with Dutch transgender actor Romy Haag in Paris in 1976, if you ignore the initial first impression and transvestigate this photo - Adam's apple, big hands, jawline, brow ridge, skull size - they both look quite similar.
