Is the display power of the charger accurate?

In my experience it is adequately accurate

I just purchased this charger, and I love the plastic battery cases that came with the batteries. Is it possible to purchase these separately?

Sorry, we do not have a separate case for sale.

If I leave the batteries in this charger and use it as a carrying case will the batteries discharge?

I do this exact thing. I don’t notice any loss of charge over a few days of storing a fully charged battery.

Does this actually with with gopro hero 9 black? the last one i ordered said it did, but it did not.

Assuming the 10 and the 9 are the same battery then yes. The picture shows an accurate image of the product I received. I like the 9 batteries better because they hold more amp hours than the 10 battery. Hope that helps. Just a note, when I ordered mine, it came with 3 batteries, not 2 as described here?
