The things/concepts that those screenshots have that infiniminer (a voxel game made before minecraft) doesn't is... grass, trees, glass. I hate to bring it to you, but minecraft didn't invent those. And it certainly didn't invent the concept of a voxel world (not that it could even copyright that if it did).

Never mind that the things in those in-game screenshots aren't even in the play store app, they're separately downloadable things.
