Here is something interesting I noticed. The yellow streak on the left of my SP3 is only noticeable when viewed from the right. So my right eye sees it, and my left eye does not. I can make the streak go away by covering my right eye.
My right eye is better close up, and I have poor stereo vision, so I'm pretty much ignoring my left eye when using my Sp3. Unfortunately this means I always see the streak at full intensity. If your left eye is better, you may never notice the stripe. If you have perfect vision, the stripe might be half as noticeable because your brain would seamlessly blend the view with the streak and the one without.
I'm not recommending you rotate your SP3 180 degrees or wear an eye patch, to make the streak go way, but either might work.
