I do not know where you heard that increased oxygen levels allows for a greater bioload, but it does not. Not even close. You may want to do some research on the nitrogen cycle.

Dissolved oxygen is a vital part of successful aquaria but it is not everything. and to answer your last question, if the water becomes supersaturated with oxygen, then it can be harmful; for example, in supersaturated seahorse tanks, the horses develop bubbles under their skin as the gas bubbles out. It is not particularly easy to supersaturate water though.
