4K is working well on KMP but Splash can't run it properly. Splash shows the movie like there is a gray filter on it, but movie's preview tumbnail thing shows movie's colours well. Also while movie is playing, I can see some pixels when movements happen in the movie like when you forward the movie in VLC player and buffers the video and during that buffering some pixels show, same thing happens in here but I don't go forward the movie, it is just playing normal speed. You can see the gray filter thing image below and also MediaInfo below.
