I'm currently watching Plymouth v Exeter and in UHD and the picture seems to be darker than usual. I have a reasonably decent LG Oled TV and have never had this issue before. I understand some cheaper TV's struggle with HDR, but like I've said normally when the HDR kicks in my picture is bright and vibrant.
Update... My TV must have had an update which set it to eco mode. Now that's off the picture is back to it's best.
