1.The 5k be is good in color and brightness, but the sde is visible. I think it is not much different from Oculus.
I have experienced 8k, 5k +, 5k be.
5k be, I can not feel the difference except the brightness.
As soon as I wrote the 5k BE, it was definitely darker in color. It was OLED, and I felt that it was colored and bright. But 5k is PenTile, so sde surely felt more than 5k +.
Because the brightness of the display is too bright, I personally feel bright and intense color, but if you pursue realistic colors, you may feel a little exaggerated color.
The pixel part is less visible than the 5k plus and looks more clearly
