This mostly makes sense to me. The only thing I am struggling with is your last two sentences. I've played with it a little bit using the ability to quickly switch between FX and DX formats on my D850. I can't see a change in depth perception when doing that. It may be that it isn't happening, it may be that my brain just doesn't perceive it for some reason, or it may just be too early in the morning. I'll keep working on it.
That convenient FX to DX comparison natcherly isn’t showing you much effect becuz it’s just a 1.5X or 0.7X change in magnification. Thaz quite mild so your human visual sensibility just adjusts for it as nothing worthy of note. Think about those early 2X zooms that were 44-86, 40-80, 35-70 etc. Basically, those 2X zooms were seen as flexible *normal* lenses, a normal lens that let you fine tune your framing ... mainly useful for chromes. Well those are 2X while your FX to DX switch is only 1.5X.
