It’s hard to tell from the photo but I would guess that you should not see any of the green EGC. Waste disposers are permitted to be cord and plug connected if they meet the requirements of the NEC in 422.16(B)(1). That means that the cord must be identified as suitable for the purpose. It’s unclear if the cord in the photo is so identified. If you really wanted to nitpick that NM connector is probably not listed to be used with that cord.
