HDR remains on after switching channels
I have the wireless 4k box (connected to LG C9 display) which has been working well for more than a year, when playing Dolby Vision 4k HDR content as broadcast by Xfinity, football amd other sports mainly.
Recently, maybe after a LG firmware update, odd behavior started. The xfinity box switches the display TO the appropriate 4k HDR display mode, but DOES NOT switch back to the non-HDR mode when switching back to non-4k content. Fix is to switch LG display off and on.
This only happens with xfinity box apps, not on LG native apps for the same content.
