Is the iPad Pro not yet on OLED? All of Samsung's flagship tablets have OLED screens for well over a decade now. It eliminates the need for backlighting, has superior contrast and pleasant to ise in low-light conditions.
The iPad that came out today finally made the switch. iPhones made the switch around 2016. It does seem odd how long it took for the iPad to switch, but Samsung definitely switched too early: my Galaxy Tab 2 suffered from screen burn in that I was never able to recover from.
I'm not sure how OLED and backlit LCD compare power-wise exactly, but OLED screens still need to put off a lot of light, they just do it directly instead of with a backlight.
