My impression is that nothing in the photos is screaming out major engine failure but of course photos can be deceptive and incomplete...
First impression is indeed 'no screams'. But it would help if we had more pictures. Especially one top down, and of course turning the engine over. With the present pictures you cannot see anything of the HP turbine and the aft end of the engine. It may be buried, but it appears to be a rocky ground with little rock and little sand or grit expelled backwards, and the fan and LP area appears to be crushed and not dug in. If they overturn the engine you would get a better answer.
The 'supposed' engine failure would have to be catastrophic, which means fast, and causing extensive damage to the engine ... and probably significant damage to the wing too. At this stage the pictures do not point in that direction. The wing halves look pretty complete. The cowling components are found close to the engine. Very prelim of course to say that, but still ...
