You show the RG/BW subpixel array photo, which is great and important info, but I don't think you emphasize enough in this article that the RG/BW subpixel array means the panel is not really 3840x2160.
RG/BW is a cheap trick to achieve the ability to advertise a particular resolution, without actually achieving the resolution itself. In a normal display, resolution means how many individual independent squares you get that can each display any color they want. Here, you don't get that. Your computer renders in 3840x2160, but your display cannot display it in proper detail because doesn't have enough dots.

RG/BW is a huge problem in the market today, and we need to address it as such. True 2880x1620 and 3200x1800 displays exist, and their resolutions provide more detail and a smoother picture at lower computational cost than a false 3840x2160, but manufacturers are opting for false 3840x2160 displays instead. It takes away our access to wider varieties of resolutions, and it invades the advertising space of devices that do truly achieve the 3840x2160 resolution.
A big step towards solving this would be to properly address it in your reviews.
