Very true, though I believe most will expect the outbound CX to perform similarly to the C1. So like me will be envisioning the CX in this comparison, which is CX £1519 vs G1 £2999.
Verdict summary (my interpretation): Yes the G1 is brighter and has slightly better contrast, but in daily life most people won't notice this as the difference is not very big.
At that price point - even against the improved G1 - the CX is still the one to buy. Once the CX stock has been depleted and it really comes down to C1 vs G1, then it’s a much tougher call.
Sure, you could say the G1 is only a marginal improvement but when that price difference is much tighter, I’d argue that the G1 slides into contention. As minor as the leap may be, the end goal is to get OLED as close as possible to 1000nits.
