Great questions! I tried doing some preliminary research -- I think the different pixel layouts are related to propriety algorithms developed by each company. I'm not super sure about the "shades" of colors either -- they may just be individual decisions each company is making! It's hard to say too, the phones/photos seen here may not be calibrated in the same way. There are some differences in OLED vs LCD layouts, but the ideas are the same. They result in some differences in brightness, color representation, and power consumption: https://www.mvps.net/docs/what-are-the-main-differences-between-lcd-or-oled/
