the final output is not guaranteed to be visually identical because parts of the processing pipeline (chroma reconstruction, tone mapping, scaling, and output formatting) are implementation-dependent. There is a spec, but multiple processing stages are not strictly defined to be identical. Higher end players also use a HDR Optimizer and the ps5 does not, which is visually noticeable.
