Others have reported, either in this thread or another one in this forum, that they have experienced the problem cross platform and others have reported it being intermittent. So far I haven't seen anything that proves the MacWorld article and the article to which it links to be wrong.
Also, I have read reports that people who have not upgraded their ATV have had the same problem.
Yes, people have reported cross-platform issues. And others haven't. Any streaming model will be subject to the vagaries of the connecting network. But how can it be a source (Netflix) bandwidth problem when I can interleave sessions and always get superHD on my TiVo and almost never get superHD on my ATV? Yes, someone needs to upgrade, start having the problem, downgrade and stop having the problem to increase confidence it's a new Apple or Apple+Netflix specific problem however I haven't seen any credible evidence that it's not.
Most people don't know how or don't have the tools to make a rigorous comparison between devices. E.g. someone observed a high ping time to Netflix and thinks that has some relationship to streaming performance.
By the way, when doing comparisons you should make sure your devices are talking to the same content farm. In my case I often connect to something in the 108.175. netblock like 108.175.43.135 (but of course that's dynamic). This is after various connections to Amazon Web Services systems among other things at startup which I assume are used for management and authentication.
