The "hands on" advantage would be to first check it's the proper No.4 cutoff and not a No.1. (Can't make out clues for sure on this monitor, and the easy areas aren't shown well if at all..)
3 minutes of "hands on" is worth days of trying to discern stuff over the internet. That's worth major premium to me.
ETA: Sometimes even smells are important. Let me know when internet gun auction sites add a "sniff" feature!
