Philips LCD TVs do not compare well against other higher end LCD TVs, let alone OLEDs. You'd need to consider one of the LCD TVs in the high tier section of the guide instead.For sure an oled is only for viewing streaming media (no logo) or gaming (but not all games), not more I think.
I thought sports could also because repetitions or half parts, the result board is gone. But the green of the stadium of nfl for example is something to think of it in an oled.
Besides these uses (streaming or gaming selected, dont know if sport), there is not so clever use for an oled, tvs channels with their logos mess up.
I compared in a retailer a lcd vs oled from philips, and in the oled it was another better quality, like it almost pop ups and more bright, the image was a car, and the car was brightened in the oled, not so much in the lcd on the contrary.
So, even it is some windows 100% brightness, it is safe, but it is a big difference if I set 85% instead of 100%, so much difference?
You can set the brightness lower if you like, but as I said you'll be clipping HDR highlights.
I think you should think about if you'll use content that is risky on the TV first, and take your decision from there. You mustn't think you can avoid burn in by running HDR with a lower peak brightness otherwise you are losing picture quality.
