First, no we're not good and you're not squashing anything. Color shift is something ALL OLED displays have. Have you ever read a review where the reviewer talks about viewing angles? They do that because all screens have issues when viewed from anywhere but dead center, and that includes OLED, LCD, and even CRT. LCDs generally white out off axis, OLEDs shift colors. That's a reality.
So, what they using is gen 4 right? It doesn't matter what they're using in their TVs, we're talking about smartphone displays, which as you said are gen 4.
I don't really care about any company. What I do care about is people spreading false information. Google's has a lot of things wrong, and they make insanely stupid decisions sometimes, same with HTC and LG.
And here in likes the problem. As I said before, all displays have issues when looking at them anywhere but head on. There is no display that doesn't have this issue. Some may be worse than others, but none are immune from it. You can try to find one with the least amount of off axis shift, but there will still be some.
I work in electronics installation and repair, so I have seen this quite a bit, whether the regular consumer sees it or not. Someday they'll come up with a display that doesn't exhibit this, but we haven't seen it yet.
