Doesn’t OLED pixel layout not line up with modern text rendering engines? At least that’s what I believe I’ve read from reports on banding around text on Windows in particular that makes long-running text work a problem.
If there are any problems, it’ll probably be with cross platform software that doesn't use native text rendering and assumes RGB subpixel arrangements instead of obeying the system.
A separate problem is that I don't think there is a standard way for monitors to communicate the subpixel layout in such a way the font rendering engine will have access to it. That seems like a pretty big oversight when introducing these in the first place.
