With all this talking about length it is far easier to remove it and see how much it bends sidways, that is both sets of sideplates on the floor and see how much "curve" you can get in it

Would be interesting to see side movement of an old and new chain side by side, the difference would be easy to spot.

Or the easier way as mentioned earlier, lift change a bit off rear sprocket if possible.
Sideways wiggle can be checked when verifying correct slack.
A riveted chain will be opened when replacing it, not before
