HDR message on Pro Box

[TIMSPORTSFAN]

For some reason as of yesteray, whenever I switch to channel 465 (Ultimate HDR) my Pro box didplays a message saying "Looks like your current TV setup doesn't support HDR, meaning you may be experiencing reduced quality. Switch to channel 433 to get the best picture quality for you."

But my TV (Samsung Q7 QLED) switches to HDR mode anyway, so I don't know why the message appears. This hasn't previously happened in the few months since I got the Pro box.

Tried fully restarting the box and TV but it still happens.

Anyone know how to resolve this?

Thanks

@TIMSPORTSFAN I was getting the same message on a Sharp Aquos but it was definitely displaying HDR so it seems like a glitch

I think that message is there when it thinks there is a problem with the stream.
