I'm blown away with the G7's image quality. After calibration, the picture it puts out is approaching my professionally-calibrated Panasonic GZ2000 OLED TV. Of course, it can't come close in terms of HDR without more sophisticated local dimming, but the overall colour fidelity, with natural looking skin tones and clear motion, as well as black levels are excellent. I have the 27" version and the only thing I don't like is the 1000R curve. I'd prefer something slightly less curved or flat. Other than that, I can't fault it. No flickering issues after applying the latest firmware update dated 2 November.
A photo taken with a camera can never fully illustrate what the eye sees (especially after JPG compression and when trying to capture HDR content), but here are some samples I've taken:
