No complaints about color volume and accuracy on the G3. Amazing panel.
G3 is great however when you have seen QD-OLED, you will notice that colors are lacking on WOLED. The white subpixel shines too bright in comparison to the RGB subpixels. This was also a problem on G2 and mentioned in the reviews for both.
This is where QD-OLED has a big advantage. No white subpixel.
Big difference between raw brightness (nits) and general RGB brightness on OLED.
QD-OLED shines much brighter in the RGB subpixels, this is why color volume and general image quality is better. Colors are pretty much lifelike where LG WOLED is more dimmed down.
WOLED biggest issue right now:
1. White subpixel drowns RGB subpixels and dimming the colors. Brightness is fine and even great (on G2 and G3, not A, B and C series, which are lacking), however most brightness is done by the white subpixel.
2. RGB subpixels has like 1/3 of the brightness QD-OLED has.
3. MLA/META did not really improve color volume much and LG seems to have maxed out WOLED tech or close. They have oppotunity for EVEN MORE white brightness going forward but diminishing returns is the problem. More white light, less actual colors.
It dont matter much if LG can hit 3000-4000 nits if white subpixel does most of it and RGB subpixels still stay at a few hundred nits.
I went from 3x LG OLED TVs (C7 -> C9 -> G1) to Sony QD-OLED (A95L) and the colors are what amazed me the most. I still use G1 in the bedroom and still like LG. However I sincerely hope that LG can improve color volume and RGB subpixel brightness on WOLED going forward, or they will have to cut prices. Slamming even more brightness thru the white subpixel is not the answer and will just drown out colors further.
Both LG and Samsung claims 3000 nits peak now.
