Gavilar's Sphere

[BrightVoid]

So after I saw something that said that the gemstone in a sphere affects the light color, I started thinking about Gavilar's sphere.  I always assumed that it contained investiture from Odium as opposed to Honor.  My new conclusion however, is that the gemstone could have corrupted the stormlight, producing the same effect as nightblood's corrupted investiture.  We have a WOB that the investiture that fuels nightblood is not gone, simply unusable.  If Gavilar had figured out how to manipulate this type of investitiure the possibilities for its uses would be huge, because that investiture would not be influenced by a shard.

Does anyone else think its a coincidence that the one person on Roshar who has the black gem/knows where it is also happens to be one person who will be wielding Nightblood?

 

I can't picture how it will go together but it does seem a little fishy.
