Thank you for saying this. Many people misinterpret DR, thinking it's some kind of a upper/lower hard boundary. It's a far more neuanced phenomena. Not only it's different for each of the RGB channels, but it also has an ugly cousin called signal-to-noise ratio. This leads to funny business in the shadows and highlights even for well-exposed photographs, particularly as the ISO raises. And, as you correctly pointed out, DR plays a role in tonal transitions, especially (again) at higher ISOs.
That 1EV gap of DR between the Sony A7R V and the Nikon Z8 one can see in charts on photonstophotos? I see the extra harshness in transitions in ISO400+ images almost every day, as I own both cameras. Yes, I pixel peep to see it, but it's there. Is the stacked sensor worth the trade-off? No fuскing way in 90% of use cases. In fact, I used to be puzzled by the enthusiasm with which the online photo community embraced stacked sensors. Why would anyone agree to trade off DR, which is useful 100% of the time, for 20fps bursts which is needed... almost never? And, by the way, you don't need a stacked sensor for a class-leading AF-C, as demonstrated by the A7RV.
I have a theory that explains this collective insanity though. As smartphones were getting better and better, fewer and fewer people used dedicated digital cameras. I personally know several folks who will list photography as their #1 hobby, who left DSLRs behind and are perfectly happy with RAW files coming out of their iPhone Pro Max. This exodus completely chnanged the composition of photo genres that the remaining MILC users practice. Everyone is either a video content creator, or an action/bird photographer now, because an iPhone still sucks at that. This shift is noticeable even in the galleries hosted here. Feels very different vs 2005-2010 when we had more variety.
Fuсk the stacked sensor pandemic, and I blame iPhones for it.
Your viewpoint on stacked sensors may be shaped by what you shoot and how you look at images, but it does not fit my experience at all. If one wishes to shoot silently, stacked sensors reduce motion distortion in subjects who are moving even at relatively slow speeds, especially if they are close to the camera and effectively eliminate LED banding in most circumstances. Moreover, according to Bill Claff's data, the stacked sensor A1 II has virtually identical PDR to the A7RV except at 320, 400, and 500 ISO, where it gives up about 3/4 stop of PDR. Given the trade-offs and all in, for my photography I'd take the stacked sensor A1 II any day. And I don't photograph birds but rather people in natural circumstances.
