Unless you have a fridge assembler from that same factory with the same materials also on ice, modern tools, techniques, and methods would make this an exercise in futility with regards to an apples-to-apples like-new comparison. We don’t even use CFCs anymore, for one.

You're sidestepping the point with valid re-herrings. If the old refrigerator's compressor hardware were left unchanged, possibly repairing the thermostat or contactor causing the malfunction, cleaning the air exchanges, and replacing the seal: based on the OPs own usage chart would have consumed equal if not less energy noting it was a dual compressor model.

Are we making an accurate comparison considering the internal cooled space of older fridges versus newer ones? Many older refrigerators were smaller, so the same power consumption for a smaller internal volume isn’t telling the whole story, but I digress.
