I get it you're fairly new at the hobby and amazed at the overall fit finish and feel of your watch. You're asking a question that many of us has asked when we first began this hobby, which is how much better can the genuine article really be. The answer is truthfully the differences are subtle but most definitely present for anyone who knows, and once you finally see the flaw it's very easy to see it again and again cuz you know exactly what to look for. Does it justify a 10 to 20 fold price difference? That's discussion I'll leave for others. Also all it takes is a check on the serial number to see that the watch is not real, and since the serial number is engraved on the rehault, sanding it down or artificially wearing it away is not an option.
As far as dial coloring and hue, that's not a significant tell. It might be something that draws a question and looks off, but that in and of itself would not be enough. Also the lume plots on a genuine Rolex dial are made of white gold versus the replicas polished silver. They are close but the white gold does have a little bit crisper shine. The lume intensity while very good is not as strong and evenly applied as the genuine, and Fades faster. . The dial font on the replica dial is thinner and not quite as well applied, giving a slight grayish Hue to it. Again not something you'd pick up unless you had a genuine sitting next to it.
The bezel font in person is a very obvious tell since the genuine Rolex bezel has Platinum applied via PVD process, versus the replica's painted. I'll give you a tell that you probably didn't even realize was present on your Submariner. The crown height is wrong versus genuine. When you look directly head-on from the dial side the crown sits lower and looks like it's sunk in and engulfed by the crown guards. there's a couple of threads here detailing this and showing examples. It's very subtle, but present. Is it something you could see on someone's wrist? absolutely not. The bezel font color is something that you can tell if you know what you're looking for from arms length. The replica Cyclops AR is not as strong as the genuine and is another tell. I can continue but you get the idea. Bottom line is overall build quality and appearance you're probably 90- 95% of the way there externally on the LN, the hulk is probably more like 85-90%. Remember pretty much any color besides black and white they get it close but never a hundred percent. I'll use my genuine and replica pelagos pictured below to illustrate this. To be honest and fair the replica pelagos is closer to the genuine than the replica submariners are to their genuine counterparts.
