I don't think those are different colorways, just some differences in how the pictures were posted. O-review only lists a single colorway like that; Matte Dark Amber / Tungsten Iridium Polarized SKU OO9246-05. There's no slightly darker variation.
Those images are CGI anyway so your real-life experience may vary.
Assuming that it's the same Dark Amber as the Ink Collection Hijinx recent release, then the colour is quite light. Think: the mosquito trapped in amber in the exposition video in Jurassic Park.
