As far as backlight leakage is concerned , nothing obvious, very few light leaks at the top and bottom of the screen, with the screen on a black background in a room with as little light as possible. The result obtained is therefore correct. The panel does not suffer from light leakage at all. The darker blacks in the center are due to my reflection. In the photo, we have increased the contrast significantly to show the uniformity of the blacks. To the naked eye, the differences are hardly noticeable.
