Auto Brightness Not Working when Powering On

Hello. Lately (possibly since the last software update on 1/13), My TV (Roku Pro Series 65") goes to full brightness when powered on. Auto Brightness doesn't engage. The only fix that works for me is to perform a System Restart. Once I do the restart, auto brightness kicks in and everything is normal. By default, I always keep Auto Brightness on. This has only been an issue recently. I've had the TV since December 2024. This issue is occuring every time I power the TV off, then on again. 

Current software version is 14.1.4, Build 7709.

To add... When I do the System Reset to make auto brightness engage, then power off and on again, auto brightness still works. It appears that the issue returns after being powered off for several hours.

I have this same issue with my Roku 65” Pro series. It works once I perform a system reset, that is until the next time I turn off my tv.

Exact same issue. Roku Pro Series 75in. Very frustrating, the auto brightness is the whole reason I bought the tv.
