When I first got the Samsung The Frame 65" 2022 model, the Art Mode has a super low brightness: perfect for night time. Months ago the firmware was updated and now the lowest brightness looks super bright, totally looking like a TV and not a painting anymore. I tried turning off all the sensors and switching the main brightness down in the general settings, but does not work to the Art Mode =/ Very disappointed that the same expensive product used to be perfect and now lost the only deferential of this TV: to look like art due to a bad upgrade.
The most likely cause of "too bright" is that the firmware update turned-off your ambient light sensor, which is needed I believe for Art Mode to work right. Make sure it's turned on and then test it by "shadowing" the sensor with your hand, or alternatively shining a flashlight at it. You should be able to drive the picture darker or brighter.
