TCL 75R617 ROKU 9.4.0 - Picture Settings problems since update

I've had my TCL 75R617 for a few months now without issue. The TV updated last week to 9.4.0 and has since been had multiple picture and settings issues.

1) Motion smoothing appears to be stuck on, even though it's showing as "off" along with all the other clarity settings. Nothing I do, even a reset settings seems to disable it, regardless of them showing as "off".

2) Picture modes don't seem to do anything. I can switch between movie, sports, normal and vivid without much noticeable change to the picture.

3) HDR/DOLBY VISION looks horrible now. Colors and details are either washed out, oversaturated or blown out. Again, when in this mode, I'm unable to change any settings that impact picture quality. It's almost as if "Gaming" mode is secretly enabled. 

Please help. The latest update appears to have damaged the TV.

Re: TCL 75R617 ROKU 9.4.0 - Picture Settings problems since update

I have an LG OLED55B6P -U (firmware ver. 5.32.00)TV and I'm experiencing similar issues. HDR via HDMI ports appear to fail auto-negotiate cfg settings and prompts a TV restart to resolve. The streaming session can also fail or exhibit audio quality issues. Content streamed directly from the LG O.S. does not exhibit these issues.

Application: Apple TV

Problem: streaming content fails to load. Tried alt HDMI ports - same issue. Tried a new HDMI cable, same issue. Re-set Roku device to factory, same issue. Re-set LG TV to factory, same issue. Appears to be a battle of system firmware.

Roku spec: model, 4630x, firmware ver. 9.4.0, build 4200
