The lenses have an amber tint, though not noticable in the above pic, even the ANH one above you can't see the amber well in it either for the comparison. The chin triangle vent is smaller as it was in ANH as well, just to name a couple things. Especially the chest box and belt are spot on ANH. Brian Muir http://www.brianmuirvadersculptor.com/
of the ANH helmet was brought in to work on this. As for the figure not being accurate. Why would they just all of a sudden do a sculpt of the tunic over the chestplate armor figure for Rogue One? It's a new sculpt, not a rehash from the Hasbro experts I've talked to. Oh and Prowse isn't in a lot the suited promo shots from the ANH era. People think he was in all of them, many he was not. I am not even sure that's him in the above one on right but I need to research more.
