If you have wondered what the differences are for the 2020 model year of the Kia Niro EV (e-Niro) versus the 2019 model, I made this comparison video that shows things in detail. If you have any questions, please let me know.
FYI: I forgot to include a picture I took of the motor model, this 2020 was delivered on May 18th 2020 and has the 710 motor.
Decided to reply in this thread to stay on topic. Thanks for checking the motor revision. That matches what I personally saw on a 2020 a few weeks back and what all 2020 owners I questioned found on their cars. In case anyone is wondering, these are not old inventory motors. They were manufactured very recently as can be seen from the date code on the motors. I assume the 2020 motor you saw was also recently built? (I posted decoder diagram previously and attached again below).

I forgot to post my 2020 sighting in this thread so here is a repost from a couple weeks ago:
Just a quick FYI. This week I saw a 2020 model year Niro EV for the first time here in the USA. Car was just delivered to my dealer and I only observed it from the outside. Didn't want to risk test drive with the current virus situation. I took some pictures of the motor and can confirm what other owners reported above - MY20 Niros still come with the original E710 motor. The manufacture date code on this motor was from 3rd week of March, 2020. Car VIN was 36xxx range. As a reminder, my replacement E711 motor was manufactured in first week of November, 2019.
