1 year, 3 months post Neograft I can see where the grafts were extracted and no progress with the transplant. Advice? (photo)

Results like this are almost always the result of an inexperienced individual performing the procedure. I’d suspect it was a technician or assistant with little to no training rather than a board certified physician with years of experience performing FUE.
The first way I can tell this is by the fact that your donor area is overharvested. On top of that, the punch they used was far too large and the punches they made were likely excessively deep leaving the above scarring. No professionally-performed procedure should ever leave results like this, especially over a year after the fact.
The only person who should be performing this type of procedure is a licensed physician with substantial experience as a hair restoration surgeon. In fact, I’d recommend people to stay away from Neograft procedures in general; they’re usually handled by assistants or technicians, the punches are usually too large, and they go too deep into the scalp in turn. 
You can see how a properly-handled donor area should look in the web reference below. As you can see, even immediately after I performed the procedure, the donor area looks clean, even & properly harvested. The punch I use in these transplants has a very small diameter (0.7mm, specifically), and the punches made don’t excessively penetrate the scalp. Six months afterward, the donor area is completely healed, and there’s little evidence that anything was removed in the first place.

Thank you for your question and photo! It's hard to tell without seeing your pre surgery photos! I suggest you go back to your initial surgeon and discuss your concerns! Best of luck!Dr Dhaval Patel Double Board CertifiedPlastic Surgeon Chicago Hoffman Estates OakbrookOrlando Park

I think your best bet for the lighter patch from your donor site would be either to have some micropigmentation done to camouflage the sharp line of demarcation, or if you are going to have a second transplant procedure, selectively take grafts from the edges of the denser/ darker areas to "feather" the results and make the demarcation line less noticable.  Of course, the easiest way is to keep your hair slightly longer in the back to cover more scalp and make it less noticable. As for the recipient site, by 15 months you will not see more changes, but without before and after photos it is hard to judge.
