Govee tv backlight 3 lite camera calibration for cinemascope

I wasn't happy with the response for scope films, so I built my own little calibration screen. The green dots are placed relativeley further to the center of the screen. It's not 100% perfect, but now I'm okay with the results. 'Alien Romulus' is a nice test, bc. it's mostly tinted red and it didn't translate to the led strips. Before it was mostly green, now I have a bit more response.
