Quick orange tint from the bottom of iphone screen just before whenever the screen wakes

So I was doomscrolling at night when I noticed that whenever I wake or turn on my screen, a very faint orange tint appears on the bottom of the screen just before the waking animation shows. It is not noticeable in a lit room at all, but it gets quite noticeable in completely dark places. For context, I have the iphone 16 plus on ios 26. Is this a normal iphone oled mechanism? It also shows the same whenever I restart the phone just a millisecond before the apple logo shows. Try it on yours and lmk if you guys have experienced the same.
