The camouflage on this prototype is probably the most straight forward I've seen in a while -- there's definitely some deformation with the roof, but it seems straight to the metal for the most part.
(Also think there's some fake cladding on the rear bumper, but that's a little harder to say for sure.)
Judging from the front shot, there looks to be possible cladding in the lower front area around the spindle grille. Also the hood looks devoid of any character lines or strong surfacing, which is quite different from the concept. So unless Lexus made the front end look much more tame and bland, I would guess there is some subtle cladding possibly on the hood area as well.
The thing is, with the type of camouflage that Toyota/Lexus uses, it's often almost impossible to tell if there really is cladding underneath the camouflage or not.
Toyota very much lost the unique contouring lines on the bonnet/hood from windshield to grille, between the LF-LC Concept's 2011 design and final production LC design. All a result of styling and engineering development from 2013 to May 2014. That is what you're seeing unfortunately. The end result of the 2017 LC design, that was frozen circa May 2014 (thank you Alain Uyettenhoven). One knew to expect changes, but I working specifically in this field, I am trying piece together why it lost anything in translation in that area.
The headlights are enclosed as always envisioned, but clearly there needed to be room for access to the 5.0 litre engine (either new unit, TTV8, or revised 2UR-GSE). The concept didn't have a real engine, so it wasn't really a factor. The LFA's bonnet/hood managed to maintain that shape, but not so much for the LC. This is what happens, when the power plant is shared with a massive luxury saloon and requires great width.
From what I remember, much of Edward Lee's approach to designing this in 2010-11, was pretty much production-feasible parameters. I am not sure what happened between his sketches indicative of that and the advanced design work that led to the final LF-LC, as clearly that had to be reverse-engineered again to the rudimentary design, plus further corrections and alterations.
If I remember, Lexus and CALTY had this problem way back in 1988-early 1989 with the original Z30 SC400 coupe, later introduced in June of 1991. Designer Erwin Lui, had to have Toyota engineers in Aichi moderately alter his concept during the early months of 1989 to accommodate the 1UZ-FE. Edward Lee seemingly has gone through the same issue in 2013-early 2014, judging by the shot of the front end.

Lexus uses the ZF 8 speed automatic, if they continue using it, they might then get the ZF 8 speed transaxle that Aston Martin uses. It would benefit the LC.
Just to correct you again, Lexus does not use the ZF 8 speed automatic. Lexus uses the Aisin 8-speed automatic, which was the world's first 8-speed automatic when it debuted on the 2007 LS460. The ZF 8-speed came to market several years later.
Those proportions look really good. Headlight shape seems to be fairly similar to the concept, especially in that picture with them turned on. I would love to see this without all of the camo.
Gotta disagree, I don't like the length of the hood. Looks too short and slopes down too hard. It also looks like the car is extremely high off the ground.
