Talking about OLED devices here (the G7 is a traditional LCD), while I haven't seen it in person the LG V30 catches my interest as well. While obviously not PWM free, the dips are low amplitude and the line stays relatively flat.

This is in comparison to the Iphone X below where only 50% brightness is desirable here.

And of course, Samsungs are just straight up trash. Note 8 shown here.
