The decoder creation for raw trace uses metadata from the first CPU. On per-cpu mode, this metadata is incorrectly used for every decoder. On per-process/per-thread traces, the first CPU is CPU0. If CPU0 trace is not enabled, its metadata will be marked unused and the decoder is not created. Perf report dump skips the decoding part because the decoder is missing. To fix this, use metadata of the CPU associated with sample object.
