I agree. It's a fair enough request, there is enough evidence out there that this is a real issue. Especially if getting warranty work will be an inconvenience.
The real question you should be asking though is do the new models have IR? Whether or not it is Samsung or LG isn't the main issue.
Unfortunately there are only a couple of regular posters here who actually have the 2013 and honestly they don't have to run the test if they don't want to (my sister is expecting one this week and she's already told me she's not even going to bother).
Hopefully the posts will pick up in a few days. Have you checked Apple Communities yet?
