If I don't see it holding it normally or pressing on the screen while holding it (which is something you do normally), then I say it isn't an issue. I'm sure if I pushed and tried to look for things I could make something happen in every product I own.
If you hold it with your right hand normally and can use the iPad without causing this to happen then I'm OK with that.
There are people on here saying they can see it just by holding it. They're not pressing on it. This worries me.
I've been looking at this forum for a while, and people always say this, that, and something else. Sometimes it's legit, and sometimes it's pure nonsense. I imagine Apple and Samsung both have people posting on here, as well as diehard fans of both companies.
After reading this stuff about pressing on the screen, I figured why not. Actually, I held the sides and pressed on the back. Nothing happened to the display. When then original Mini was first put on display at Best Buy, I saw a kid really pushing on the screen. The screen had that puddle effect while he was pushing, but immediately returned to normal when he released his pudgy finger. I tried it, and the same thing happened. It took more pressure than a reasonable person would use on a tablet, and I bought a Mini the next day (and used it daily for nearly a year).
Sift through the threads and posts, but do so with a HUGE grain of salt. If you see someone making outrageous claims, look at their past posts. If someone joined on launch day, and has made nothing but negative posts, you know something is up. My wife bought an iPhone 5S on launch day last year, and someone started a thread about the compass and level not working properly. We weren't aware it had either of these features, but the thread grew and grew, and had around 1,500 posts after 10 days. I finally gave into the fear that this might through off the GPS, etc, and we returned the phone. A week later, it seemed a software fix solved the "issue". My wife really wanted that phone, and used an HTC until we each bought an iPhone 6 on launch day.
