I didn't find any big changes either, measuring high-voltage
electrolytics from as far back as 1947. Looking at your data, within
the limits of experimental error I don't see any changes at all. That
pretty much kills the myth about capacitors reforming to a new working
voltage and changing the oxide-layer thickness.

However I'm sure we haven't seen the last of it. I believe there's
still a website with quotes from Deeley's book on electrolytic
capacitors. What it doesn't say is that this book was published in
1939.

One site has much of the Electrolytic Capacitors book online, but it
does carry a disclaimer:

"Great strides have been made in all aspects of capacitor technology
since Electrolytic Capacitors was published in 1938. Most of the
material presented here at this time is directly from the original
edition. The reader should therefore be cautious in regards to the
technical veracity of any claims herein. "
