Okay, last night while I was reading in bed, I adjusted the brightness even further to 9% and could still see the streak.

As my eyes adjusted, it became even more prominent. (Did about 5 hours of reading last night + this morning.)

While my eyes read the:
  • Text on the left. I noticed it out of the corner.
  • Middle, not so much.
  • Text on the right. Definitely noticed it.

So I was continually just subconsciously flip-flopping. A little frustrating.

I took some photos of my screen in the complete darkness.

Note: I am no good with cameras/exposure. So I admit it's a little tough to see in the pictures I took. Looks WAY different in person though.

Brightness 75%:

and here's one where I adjusted the gray levels (of 25% Reddish) so you can clearly see the streak:

In the daytime, and "normal" lighting conditions, I'll have to admit it's not that noticeable.

But I do almost all of my reading at night, in the pitch black, under the covers.

I force the device into Portrait mode, lay it down on its side and prop it against a pillow, and lay sideways while reading with my head propped on my other pillow.

With the fat edge on my left, the streak was much less bothersome. Maybe it has something to do with all the lines starting at the streak, so my eyes just drift away and I can ignore the streak.

When I tested the opposite, with fat edge down + my eyes heading towards the streak, then it was bothering me.
