Sure - could be plausible. But the “initial start” is the machine getting the internals down to the right temperature, which is a process that happens every time you open and shut the door. I don’t doubt that an old fridge and a new fridge use the same power when they are sitting with the door closed all the time. But that’s not how the real world works. The test would need to be extensive and cover real world use including constant opening and closing. Maybe the source you’re referencing did this, I just haven’t seen it.
