Scratched Screen on Apple Watch Trade-in

I want to trade in my Series 3 for a Series 4. It is less than a year old and in great shape except for a small scratch in the lower corner where it is not too noticeable when using watch. On the trade-in screen on the Apple website it doesn't differentiate between major beat up watch and screen scratches; if you check anything but perfect, you just get an offer to recycle. Does anyone have any experience with trading in an Apple Watch with minor scratches?
