not since WIN lost the court case 
two different resoultions:
UHD 4K is 3840px x 2,160p scan lines 4K DCI is 4096px x 2160p scan lines
Big difference in bit & frame rate also, but that said I doubt we will see 4K DCI anytime soon , not many mobile devices can do DCI standard recording, my device can and it looks awesome but gees it consumes HDD space with its whopping 55Mbits bit rate, it’s almost like capturing RAW vision.
