Finally traded in my SP3 with the light bleed and the yellow streak for a shiny new model at Best Buy today (god those guys must hate me). This is Build number 1430. So far NO yellow streak and NO light bleed. Whew, so so happy. But there is something else. The whole computer just seems "different" now, different as in "better". The screen looks better, colors pop more, fan almost never runs, text looks smoother. Hard to say what it is but it looks as if they may have fixed some of what was broken in these later builds. Another owner with Build 1432 commented they had no yellow streak either. So, if you are still in your return window and you can make an exchange, see if the local Best Buy has any builds 1430 and above and go for it. Good luck.
