Also seeing the Roku staying on forever when I power off the TV and receiver or switch to another device.
Hopefully this gets worked out. Don't want my World Cup viewing interrupted.

I have the same issue with the ROKU and stand by issues ever since the update. I can't make any sense out of it. It does in fact to be an HDMI related issue, however fully disabling CEC on the TV, and ROKU don't solve it, and I thought I had it fixed this morning by leaving the TV set to a DIFFERENT HDMI port when powering off (one other then which the ROKU is connected) and while that seems to keep it asleep while the TV is on, as soon as the TV is turned off, it wakes back up. It's strange because the ROKU port isn't the active port when the TV is shut off.
I thought it was related to which screensaver I had selected, but it doesn't seem to make a difference. I have thought about disconnecting the HDMI cable from the ROKU itself while the TV is off, to see if it's even related to the HDMI connection to the TV at all, or if it's something internally going on that doesn't matter if it's connected or not.
Thankfully, I haven't had any streaming issues, or HDCP errors, it just won't stay in standby no matter what I do. This doesn't even seem to be a 4K specific issue either, The Premiere+ that I stuck in the bedroom for the 1080p setup, has the same issue when it comes to stand by, and CEC is completely disabled in there. The only two devices that have it, and can't have it disabled are the sound bar, and HDMI switch, they only activate it if they detect another device in the chain that has it enabled. So with everything having CEC disabled that can have it disabled (including the ROKU) HDMI weirdness shouldn't be happening in there like this.
