Hi. After a little more than six months of ownership, my OLED55G46LS spontaneously acquired a new behavior. (Almost) every time I turn on the TV, after a 10-15 second delay, it opens the Home screen.

• Power On Screen is set to Recent Input, not Home. When I turn on the TV, it does open the recent input, which is normally HDMI2. But after a short delay, it opens Home anyway.
• Quick Start+ is turned off.
• There is no Home Auto Launch in my Additional Settings, so nothing to disable there.
• Automatic Updates are turned off. This made me extra surprised that the TV changed behavior overnight.
• In an attempt to fix the problem, I manually searched for updates and installed a new version of the OS. That did not help either.
• I use a Harmony Elite with a hub to start and control the TV, and a Denon AVR-X4300h connected to the HDMI2 output of the TV. The Harmony software doesn't let me spam the "change input to HDMI2" command after startup, so I'm stuck with trying to make my TV revert to behaving like I believe it should.
• If I turn the TV off and on again, it seems to open the recent input and it doesn't go to Home. But when the TV has been off for some time, it does go to Home after startup.

I am stumped. Any insights or tips would be appreciated. Did I miss something?
