I'm assuming there's some problem with screen-rendered QR codes that this solves, but my quick google search mostly just resulted in listicle spam.
What's the problem this solves?
I notice some airline apps and Google Wallet set screen brightness to maximum when you view a boarding pass.
When I look at the two codes side-by-side with normal (full) brightness, the HDR one looks quite a bit brighter. If I dim my screen brightness substantially, the HDR one also gets a lot dimmer. Not sure if this solves that problem, though it could be an issue with my particular screen?
If I dim my brightness completely the HDR does get dimmer but is still quite visible while the other is quite hard to see.
I may make a difference with laser scanners or other more commodity hardware than smartphone cameras which are pretty amazingly good these days.
