On OLEDs, high levels of ambient light hitting the monitor tends to wash out blacks, making them appear dark gray, thereby subverting one of the most clear-cut advantages of OLED.
I don't see this on any of my phones or wearables. I'm aware QD-OLED in particular has this weakness, but haven't heard of or experienced any other OLEDs having this issue.
I wonder if it's actually due to the quantum dots, or if it's more broadly a thing for large OLED panels. I haven't spent any significant time using an OLED TV, and I think most of the OLED computer monitors I've seen in person were QD-OLED.
I don't know the mechanism behind it, but I've done side by side comparisons and it's clear to the untrained eye that the impressive contrast ratio of OLEDs is easily weakened by ambient lighting conditions.
