My tcl 6 series R625 I think tcl fixed the backlighting issues I was having, any hdr mode works like normal or bright without any issues. The picture looks great with dark blacks on Normal picture mode or hdr bright with warm color and color at 40 and tint at +2. I am having no issues with the picture like I did before. I did use my wife's iPhone 11 for the IPQ app and it worked. Love the tv now
