It's just a boot screen so maybe the screen itself or it's electronic board been replaced maybe an Asian market car etc . Who cares boot screen . All else functions normally . Nope don't know how to change
Someone was able to access the system and replace the boot screen image... This is how people first learned to hack Hondas at the start of the 2000's. Toyota has thus far been locked down too much to do what Honda hackers can do, but this photo gives me hope. Or maybe its just the wrong ECU? @SFO or @ChapmanF what ECU controls this screen? Does a Lexus have the same plugs?
