Yes, you can see it in the model image above the picture of H.R Giger's Alien.
Or look at the Isolation Alien on Google Images.
Even the shape of the back pipes match up to the Isolation version, but not Giger's Alien.
The dorsal spike is larger and longer than the pipes on Giger's Alien, on the Isolation version it's the other way around-
The headrest dorsal spike is much smaller which matches to Tristan Jones' image.
