Update.
Just got my computer back. Even though the technician advised me that my replacement keyboard would be exactly the same version that I had previous because it shares the same Apple part number for a Late 2016 Macbook Pro, I can say with confidence that my keyboard is a 100% different keyboard than the original.
Noise Level
The noise level from typing is subdued enough that it makes a noticeable difference. The sound when typing is not as high pitched and 'clacky' as before it is now deeper and much softer. I can finally type at night without having to worry about waking up the baby or during a meeting without having people giving me awkward looks. I'm totally serious here and not overreacting.
New Keys
The control and option keys are the newer 2017 US version. There is some debate on this as my replacement happened outside of the US and the technician informed me that Apple supplies them with International keyboard versions. And I have read that some people in the US are getting the exact same keyboards so YMMV.
Lower Profile
The keys also feel different when typing and I would venture to say, lower profile with less travel needed to push the keys. This difference in feel is VERY slight but is also noticeable having been on my 2016 keyboard for 1.5years+.
Extras
Also important to point out that with the keyboard comes a sparkling new topcase, trackpad, battery (2 cycles, 102% health, manufactured Nov. 17, 2017, 8.1 months old) and new speakers. Sweet!
Sticky Keys
Of course since it is new I don't have any issues with sticky keys... yet.
