In the past GEs have come with a resistored magnesium anode. The resistor lowers the driving current to the level of aluminum to ensure that the tank makes it through the warranty period.
Peroxide isn’t about disinfecting. It’s about adding oxygen to the water that anaerobic bacteria don’t like. But if the anode is the problem, the odor will dissipate immediately upon removal. Adding peroxide just ruins the test because that also will make the odor dissipate immediately.
A softener is reason enough to add a powered anode for the reason you mentioned. And aluminum/zinc only occasionally solves odor problems in softened water.
Not sure about the discolored water unless there is some galvanized piping on that line.
