Bought a brand new roku 4k+ streaming stick today. The entire thing is black and white. I've tried all the ports and none of my other devices have this issue. The roku stick that I JUST bought is the only device that has this problem. I truly can't believe this problem still exists and you've done nothing. I have a Samsung smart TV with HDR10 support and have it plugged in through HDMI. THIS IS COMPLETELY FALSE ADVERTISING WHEN I BUY A NEW PRODUCT THAT HAS BASIC FEATURES THAT DONT WORK.
