I have a 68 eldo with 472 and I think the 472 was with a gold air cleaner. the 70 eldo had a 500 cu inch with black air cleaner. I see in the photo you are missing the v shaped bracing pipes that apex at the center back of the engine bay and angle out and attach to the top of each fender at the two holes noted on top of both fenders....I will find a picture of the 472 I have as a screen saver.
Regarding the level of gloss on the inner fenders: I have a '70 as well (DeVille), as does a friend. On both, when cleaned up, the inner fenders have a good deal of gloss to them. Both are original paint in the engine bay. It's not quite a full exterior gloss (say about an 80 percent), but is far more glossy than most satins, and is definitely NOT a flat. Core support is the same color.
BTW - from your photo, it looks like your valve covers are the proper color
Sorry, I missed the part about the photos being googled images. Best I can tell, and I've owned three of them, the car in the photos is mostly accurate. First, the photos are of a DeVille (as in convertible). The drop tops don't have the struts between the center of the cowl and the inner fenders. What stands out as non-stock are:
1) battery cable is the wrong color (every one I've ever seen that hadn't been completely hacked had a black cable to the starter).
2) The suction throttling valve coming out the evaporator has been upgraded (not a bad thing, just don't use it as a reference).
3) I've never seen one with a gold-cad brake booster and master cylinder cover.
I'd love to have my engine bay looking that good. Mine is a rust bucket sitting out in the snow. But I'd drive it cross country tomorrow if I could get around to fixing the auto-climate control head as there's no heat coming into the car at the moment.

Re: Under hood colors?
As for the 472 air cleaners, there were some variations in each year the engines were produced. One was an anniversary year and may be the one that was all gold. I'M not sure what year the one I have is, but it was all black with gold script "472" and chevrons down the snorkle.
