In the first movie we see Cybetron with transforming towers covered by corpses over a land of rivers of what is presumably. Come DOTM we see a honeycomb like layer upon layer of Cybertron. This seems to be reinterpretation of the cartoon G1 Cybertron. G1 Cybertron has large fissures, cities, towers with many layers underneath. If Star Wars' Coruscant is city covered world movie Cybertron is nothing but cities. Now to reconciliate the two movie depictions of Cybertron I'm gonna assume the side with the bleak atmosphere is the Decepticon territory or some wasteland.
