You are getting confused, UBlue is the base from where all images derive, Bluefin is it's own thing, gnome or kde, Bazzite is it's own thing, gnome or kde
Kinoite and Silverblue are basically the same too, but for some reason, Fedora decided to give different names to each one just due to the desktop environment they use, but really that's only the case where the image name changes due to that
having an issue where the colors are super dark on my steam deck (lcd) in game mode. i turned on "force composite" in the developer menu and that made it stay consistent (before turning this on, while in a game it would go dark after doing something like moving the mouse, and then return to normal after a few seconds of no input) but unfortunately it's displaying the very dark colors and not the normal colors. also, the sliders in the display tab don't do anything. night light in KDE is off, and the color profile in kde is set to the default valve one
