Ten years on IPS and then two days on this is the framing owners keep reaching for, and it explains why the loudest praise comes from people who had never owned an OLED before. Motion at 240 Hz and per-pixel black are the parts nobody argues about.
Everything contested is about light and colour. A green cast, worst in HDR, comes up again and again, with owners pulling the green channel into the low 40s and still not being satisfied; others report a yellow tint that the colour-temperature presets will not clear, and the Gamer 1 and Gamer 2 presets are widely described as inaccurate out of the box. Brightness is the other half: coming from a bright LCD the drop is startling enough that one owner concluded the panel only looks right with the lights off. HDR attracts its own complaints — banding and a lifted black floor under the Windows calibration profile, and colour-heavy bright scenes looking washed because the white subpixel is what does the brightening. Against that, the matte coating is the reason several owners chose it over a glossy QD-OLED: with a window to the side, matte keeps the blacks black where glossy does not.
The upgrade question that comes up constantly is this versus the older 27GR95QE at a couple of hundred less, and brightness is essentially the whole answer — owners who returned the older panel for being too dim bought this one specifically for that. LG has also told owners there are no more firmware updates coming for the older model, which shifts the calculation. Buy it for a controlled-light room and competitive play; anyone wanting a bright desktop or accurate colour out of the box will spend the first evening in the colour menus and may still not get there.
