RPi3 and RPi2 are essentially the same device but RPi3 uses a newer generation of the core SoC that runs at higher clock speeds. As the hardware is so similar we can use a common kernel/OS image that supports both devices. One quirk of the Pi firmware in this configuration is that 64-bit RPi3 hardware reports itself as a 32-bit RPi2. It is possible to make RPi3 run a 64-bit image and report CPU etc. correctly but this requires you to run a different kernel configuration, and then Kodi doesn't run as nobody 64-bit ported the mountain of very highly optimised 32-bit video code that Kodi depends upon. TL;DR - it's a cosmetic issue and there's nothing to see, move along please
Thanks for this helpful reply. Now i understand
