I had to do the vast majority of what you listed during OW. Ex. Take BCD off underwater and put it back on.
Remove & replace the BCD underwater is a required part of the PADI OW course; it is a skill performed in confined water (e.g. pool), but not one that students are required to perform during an open water dive. (You should have noticed that there are a lot of skills required in confined water, but only some of them were repeated in the open water dives. The full list of all these requirements is in the student manual for the course.)
If you didn't R&R your BCD underwater in the pool... a corner was cut from your OW class.
