This is a known issue with (I think) certain brands of the mini leds. It has to do with the amount of power draw being reduced with LEDs and it not being enough to tell the triacs on the board that things are 'off'.
I was able to fix mine for the most part by replacing one or two of the more inconspicuous bulbs with incandescents. You can further reduce the impact of the colour difference by painting those bulbs with heat resistant glass paint the same colour as your leds.
