bolt display black screen when changing channels while in HDMI UHD mode

ok so my 4K tv (samsung KS9000) offers a "HDMI UHD Color" mode which states
"An HDMI connection with HDMI UHD Color set to Off supports up to UHD 50P/60P 4:2:0 input signals,
while an HDMI connection with HDMI UHD Color set to On supports up to UHD 50P/60P 4:4:4 and 4:2:2
input signals"

the tivo is set to 4K (2160p 60fps or 2160 fps

I do have this hooked to a AV receiver but it does the same when going directly to the tv

i just get a short 1sec black screen when i change the channel, is this the tivo trying to change the resolution?


HDCP 2.2 is enabled

i can turn off the feature and all goes back to normal but since normally this would go through the receiver I would like to have this feature enabled unless i don't need it at all
thank you
