The reason the colours look flat and dull on the trailer version is because Disney didn’t convert the HDR trailer to SDR for RU-vid, you can find a HDR version here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-hjxYVLNjDpc.htmlsi=XZdwe2AnWZFcv7bm
When the properly converted version came out the only different I noticed from that to the broadcast is a lens flare is added to the scene where the doctor says give me the loving so it’s good to know how far in advance they do vfx
