Probably these 0.5 GB it will also be available to PS4 OG/Slim after their November firmware updates. Sony always shrinked the OS footprint over the years.

That would make sense, I don't know I just expect they would announce that if true, but that's probably too logical.  
Honestly, you'd think they could have pared down the OS reservation more by this point, especially as they don't have the "snap" like MS.
(AFAIK, there actually is another 256mb pool that is rarely mentioned, that could be increased for stuff like video streaming/ screenshot)

Sony's bread and butter isn't software engineering.
This is why the Xbox has always had the advantage in OS footprint on it's consoles, which was true with the 360 and is true with this generation too.

The end results though speak for themselves, the difference in gaming ends up being neglible to non-existent it seems.

The 256Mb memory pool is associated with the ARM chip for background/OS tasks, whilst it could be increased, there is probably minimal benefit in doing so.
