I see no signs of shrapnel damage. As some said much earlier in this thread it doesn't look like an uncontained disk rotor. Nor do I see signs of extreme pressure release (some call this an explosion). Instead the pictures of the externals of the engine pod and wing go hand in hand with a persistent ground pool fire.
The photos I've seen of the engine are severely underexposed in the damaged area. Using Photoshop to bring up those areas, it's apparent that the cowling is shredded front-to-back (moreso at the back) at around the 7 o'clock position (viewed from the front), with torn metal sticking down, and that the rear edge of the cowling is missing from the inside of the pylon to roughly the 7 o'clock position (viewed from the rear). Whether this qualifies as 'shrapnel damage' I don't know, but it certainly looks chewed up.
