Update
So when I got a chance, I took the joycons off of my switch and put it on a flat table. Sure enough, there was a SLIGHT "bend" where the game card side of the switch was not perfectly flat.
We are talking like a millimeter here and the console never felt hot to my knowledge. This could easily be something out of the box and nothing more than cosmetic. I will keep an eye on it to see if it gets worse, but I still don't think this is a "warping" issue like some people try to say...though the topic does have my attention now.
