We have watched two full seasons of NHL playoff hockey and plenty of football too. Those event always have static logos and such although during breaks they go away.
No signs of any issues on my set. We also watch a ton of movies and A good amount of TV shows. No cable news though, why bother with that crap?
If there is no panel to panel variation then the only explanation is that we are simply ALL going to get burn in eventually or those that did get it are lying about their use cases and have abused the TV or watched too much logo heavy content. Right? So that means I’m going to get burn in regardless of what I watch or do? I hope not. Or, maybe I’ll have moved on by then to a new set.
It's hard but not that
Take whatever static element you are concerned about (ie: NHL Playoff Logo). Estimate how many hours it is displayed in an hour (ideally, get the stopwatch on your phone out one evening and start and stop a timer so your estimate can be accurate).
Estimate how many hours per season/year you watch of that content.
Now you know about how many years it will take you to watch a cumulative 100 hours of hat static element.
From there, it gets a bit trickier because peak luminance / OLED Light comes into play.
If you happen to have your peak illuminance calibrated to 175 cd/m2, like the 2016 rtings.com test: https://www.rtings.com/tv/learn/perm...rn-in-lcd-oled
Then it's easy to be quantitative: by week 4, signs of burn-in are clearly visible, meaning 4x7x20=560 cumulative hours. Very mild signs of burn in on red are also vidible by week 3, corresponding to 420 hours. So lets say 500 cumulative hours at 175cd/m2 of bright fully-saturated red will cause burn in on a 2016 WOLED.
Take 500 hours, devide by your estimated bright red logo cumulative hours per year and you get how many years it will take that viewing behavior to cause burn in.
Green and blue burn-in more slowly than red, so you need to find how many weeks caused the burn-in level that concers you for thise colors on the rtings test and adjust accordingly.
And time is roughly linear in peak intensity, so at 350 cd/m2 (OLED Light = 100) red could develop the week 4 level of burn-in by week 2 or 280 hours while at peak intensity of 130 cd/m2 (OLED Light ~25), the week 4 level of burn-in should not develop until over 700 cumulative hours.
In my case, the red Netflix startup logo is one of the static elements I am concerned about. It may be displayed for 10 seconds whenever we turn on Netflix, which averages less than once oer day. So less than 3650 seconds or ~1 hour per year.
I have my OLED Light at 40 meaning well over 500 cumulative hours before I need to be concerned with burn-in. So we can watch Netflix like this for 500 years before we have anything to worry about
I doubt the NHL playoffs are anything to worry about, but the entire hockey season might be.
For example, if you watch each and every game of your favorite baseball team and they have a bright red, fully-saturated logo, that translates to alot of cumulative hours per year:
162 games X 2.87 hours / game X ~75% static element display (accounting for adds) = ~350 hours per year.
At 175 cd/m2 peak levels, you should develop first signs of red before 2 seasons are over.
Any static elements that have two positions for 'Home' and 'Away' would halve the cumulative hours per year and so would extend the time to visible burn-in to just over 3 completed seasons.
And if you watch at OLED Light 100, it would halve the cumulative hours needed for first signs of burn in, so even a 50%/50% Home/Away rectangle should demonstrate first signs of burn-in before 2 seasons are completed...
