Yeah I would honestly try for a different iPad. I redid the test 6 times and every time it's fine.
Why is this problem so inconsistent?
Out of interest, what's the first 2 letters of your serial number? Is it DM?

Ok so I tried example 4 and twice there IS a very slight weird brightness amplification. So I guess mine isn't immune after all. It's very slight though, and no weird home screen icons thing.
Regardless, I'm pretty anal retentive about screen quality. It's probably a good thing I don't use Apple apps to watch videos. I'm jailbroken and use Rush Player + since it plays everything and uses hardware acceleration.
But yeah, I'd be pissed if I used nothing but Apple's videos app!
If you watch a long movie, it can get annoying after a while especially if its relatively dark because it keeps getting brighter and darker.
Yeah, I can definitely see that being annoying. Is it confirmed that it only happens on apple apps?
I think it happens on some other apps as well. Various people have reported finding this problem on different apps throughout this thread.
However, I've noticed that during videos where there are dark scenes, the iPad 4 contrast is constantly "pumping" itself up, and then dimming back down. It's unbelievably distracting. Even stranger, if the contrast pumps itself up and at that point you close the app/Safari, the entire home screen looks completely over-saturated until it, too, gradually brings its contrast level back down.
Ok. I'm downloading the same example video I used so I can test it with Rushplayer+.
Like I said, I'm pretty anal about screen quality; if I get the same results on Rushplayer+, this iPad is going back!
Regardless, I'm glad I read this thread so soon after purchasing.

Ok wow. That is incredibly annoying, playing it on Apple's video app! I feel like I would get a migraine watching a whole movie like that!
Thankfully Rushplayer+ has no problem whatsoever, so if you are jailbroken, I would definitely recommend getting this free Cydia app. Not only does it not have this incredibly irritating problem, but it also has smoother playback.
My 27" iMac also 'blinks' at times... It's faster, but is like it is constantly over reacting to the ambient light in the room, and constantly over and under correcting... It's not annoying, just odd...
The annoying part even for JB'ers is if you watch a YouTube video (say while browsing reddit on safari or alien blue.. as there are lots of redditors out there myself included), it triggers the dynamic contrast issue.
Turn the ambient light sensor off, then? My 2012 iMac doesn't do that...
Just looking at Apples history of problems you can see that display problems have been a repeated problem for them.
1st generation iPod Touch "inverted blacks"
the current retina Macbook Pro with image retention issues
Powerbook G4 defects (inconsistant back lighting)
iPad 2 back light bleeding
iPad 3 inconsistent colors
2008 Macbook Pro screen defects
2007 iMac gradient display issues
If Apple wasn't so easy to deal with I wonder if the company would have as good of a rep as they do because apparently around 2007 they decided to fire their quality control team.
Have you tried ProTube HD from Cydia? Maybe that would help?
I no longer have the iPad 4, but I don't think that would help to be honest.
I returned it to Best Buy. Since I'm a reward zone member I had 60-days to return
But I sent it back after a little over a week
