Lost Items Wildly Question

Want to understand better if this is correct?

Was at Calvarion and disconnected triggering a PVM death. Woke up in Lumby with my 4 protected items. Returned to the Calvarion den and looted the grave which gave me the items that had been stored in my looting bag + tradeable worn items (monk's robes, climbing boots).

What I didn't recover were supplies (blighted restores + blighted foods) and some non-tradeable items (seed pod, myth cape, rada blessing).

I'm going off of past experiences and I had thought if dying a PVM death in wildly and returning, those items would all be included in the grave?
