Bubbles on plants immediately after a water change, or for a day or so thereafter, have absolutely nothing to do with CO2 injection and/or plants producing O2, and hence are not pearling.
Its simply the release of suspended O2 in the water adhering to whatever surfaces are available.
Take a brand new tank, fill it with water, look at the bubbles on the side. Its the same thing.
