Well, not really.
Look at it another way. I own the gen 15711OI diver, but I hardly ever wear it. It is in my collection for the sake of collection, and I am not a fan of the diver personally. It isn't a model I enjoy wearing, or discoursing over and the 15703 is a watch I will never buy, whether in gen or rep. I do not stop guys like repworld or anyone else claiming what they claim, but I see what I see and but prefer not to spend time discussing the differences, as the latest iteration of the JF or ZF diver is a very good rep in real life. Is that not sufficient for you?
What it really comes down to, sir, is you being convinced that the 15703 (or any other rep watch you want to buy), is not worth getting in gen, and that is a very individual and subjective decision. What is even simpler than what you mentioned, is you liking the watch and buying it. If you are unconvinced of me being able to call the latest rep divers (JF, ZF, or whatever hybrid you can find) out, no problem, post any wristshot and ask me. I either will get it right or I won't and it will either prove or disprove my point. But that shouldn't change how you feel about this specific release. If you think its 1:1, by all means buy and enjoy it. Your opinion did not feature for any of the watches I chose to purchase, and likewise, mine shouldn't as well if you think that a rep is awesome and suits your every need.
What I wish to say can be summarized in a simple sentence: The V10 diver and ZF divers, while not perfect, are both very good reps in real life and sufficient for anyone seeking to get a feel of what the AP diver is about.
Have a good day!
