50X90S, latest firmware.
The "Apps" picture category appears to be bugged after the TV has been off for a short time. The colours are slightly oversaturated, and adjusting the Colour Space setting has no effect. Apps affected include Plex and Paramount Plus.
It can be corrected a few ways: restarting the TV, switching to an HDMI input and back, or simply opening an app that falls under the "Apps (Video)" category, such as Netflix.
Not sure when this bug started.
