Looks like Samsung is putting some effort into design cleanliness. Not something they're exactly known for. The question is whether they're giving the UI a genuinely fresh overhaul, or are we seeing a friendly face with the same Samsung clutter behind it?
It is worth mentioning that the "Samsung clutter" does enable a lot of niche uses for users, but it certainly doesn't lend itself to a clean user experience.
Knowing Samsung, this leak is accurate (probably even intentional). I would also bet that the same old pile of (many useless, some useful) features are present somewhere.
