We have 3 4K televisions and PQ is outstanding. And yes, I have calibrated my main LG OLED 65 set to my preferences. No difference with the Plus, if anything it looks better. (2) TCLs in other rooms that look great. It's been a great upgrade for our family. Love the new interface. It's been super smooth on all the streaming services, which I can't say was the case with the Fire Cube, which had to have frequent reboots or cache clearing. Be careful, as the loudest voices may scare you off from a strong upgrade. If there are people like myself with positive experiences out there, there isn't much reason to come here and post that things are working well.
