Odd 5S display... "issue?"

I experienced something quite odd with my iPhone 5S.

I was watching YouTube videos, and I happened to come across a very funny Kevin Hart clip (he's a comedian). https://www.youtube.com/watch?v=mANr2ode-n8 (Warning: profanity)

I was watching the video, and closed my McTube app at about 1:45, and I noticed that my entire home screen looked entirely washed out! Everything looked seriously faded for about 2 seconds until the screen came back to normal. I can repeat the issue too, so it's not like it was a random occurrence. I can keep applying the same effect to my screen! In fact, you don't even need to watch the video. I just discovered that if you leave the video paused at 0:00, close the controls, and bring them back up, you will notice the washed-out effect. Quickly go back to the home screen and you will notice that everything looks washed out for a little bit.

Curious, I go back to my 4S, watching the same exact clip and leaving the app at exactly the same time - no washed out effect.

Is this due to a poorer quality screen in the 5S, or just an effect of using a different type of screen (I know the screens of the 4S and 5S differ significantly)?

I think an issue similar to this was affecting the 4th generation iPad, something about watching a video at a certain part and then quitting the app, only for the display to behave oddly.

The exact same thing happens on my 5S!

UPDATE: This is starting to happen with other videos that I normally watch, and I don't remember the issue occurring like it is now. Should I just get a replacement?

 

114 views and no reply... Has anyone else experienced this? Or perhaps test the video I sent a link to? You don't HAVE to watch it... Just pause at 0:00. You have to be using McTube, a free app, to do this.

 

Last try, can anyone else replicate this effect on their 5S/5/5C? If not, is there a term to describe what is happening? I'd like to investigate more on the issue.

 

Thanks a bunch for your reply! I felt like my thread was being completely ignored

So, I'm guessing this is more of a "feature" than anything? It doesn't happen all the time for me either, but it's still weird...

Do you have a term to describe it?

 

Happens to me at all brightness levels :/

I have reduce motion enabled, but the same thing happens when it's disabled.
