Apple Watch series 5 burn in

So I’ve had my Apple Watch series 5 since launch (less than a year) and I just saw that my favorite watch face has burned into the display.

I know that OLEDs are nutritiously bad in regards to their burn in, but I Just assumed that these issues would have been ironed out for the always on function in the series 5.

I’m just wondering if anyone else is experiencing this with their watch?

I took two images of the watch. One with the watch face that shows the burn in the best, and another one that shows the watch face that is responsible for the burn in.
