By comparison to the Samsung Galaxy A series this is unimpressive. Everything in that line is either 2 OS upgrades/4 years of security updates or 4 OS upgrades/5 years of security updates. That's all the way down to the A03s which is <US$100.
Those are from the release date of the phone, but I think they're doing roughly annual releases on that line.
Edit: Samsung also planned for longer device life - there's an option to turn on a battery saver feature that caps charge at 85%, which should significantly increase the years of service from the battery.
