The Skyactiv 2.0L uses 15% less fuel than the old 2.0L Mazda engine. Partially due to friction, but it is also direct injected, higher compression, and has improved VVT. So, who knows how much is due to friction. Also, I'm sure significant design changes were made to reduce friction rather than just a surface finish.

So, can it help? Yes. Is this particular process worth doing for improving fuel economy and an existing engine? Very unlikely, unless it is cheap and you are rebuilding the engine anyways. And the prices you posted don't look cheap to me...
The intent is at some point to rebuild; but for now, I'm exploring potential options.
