Neosoul and Smooth jazz

So on a serious note... WHAT is it that differentiates smooth jazz from what's being called "neo-soul"? The way I see it, smooth jazz progressions tend to cycle wway more tightly around a tonal center whereas "neo-soul" might have a whole different key/scale PER-CHORD, like some subgenres of jazz. But the chords, voicings, instrumentations, and overall sound impressions/sonic imprints can oftentimes be exactly the same making them nearly indistinguishable.
 
What gives?

Smooth and cool. Miles

And Miles.

All I know is I tune my bass "close enough for Jazz".

Smooth jazz is late eighties early nineties poofy hair oversized suit jackets in solid colors like magenta and peacock blue and the crowd overclaps for everything especially the  cheap sounding korg  M1 synth solos
 
Neosoul is exactly the same with better synth pads and dressed down clothes made to look street and the crowd checks their phones 50% of the time and wants to the rest
