Well, I'd argue 1.90 is closer in shape to 2.35 anyway so...
Disagree. And I'd imagine half the people working on a film like Dune (i.e. the sound crew) would also disagree. It's the whole experience.
Or I could watch it at work in what has been described as one of the top 5 private screening rooms in Soho for free
With respect, I didn't need to. But having watched it, firstly he saw it in IMAX at 1.90 anyway so not a huge difference from Dolby. Certainly more 'widescreen' e.g. traditional shape than true IMAX. He shows some pics
here which demonstrate exactly what I have been trying to say that we don't know how they cropped it for either ratio. As-in, it's not necessarily the case you get "more" top and bottom in comparison to Dolby or 1.90. And there's more highlights/detail in the Dolby presentation. Mind you, all in all it's not the best video because he's not comparing true IMAX. And he's just comparing two specific theatres, like when he's talking about bass.
He also speaks at length about the whole experience of the cinema, crappy IMAX seats that are uncomfortable, older screen, look at that carpet etc. That whole experience matters more to me when I pay to see a film, than getting another metre of sky above a characters head
Anyway, like I say. It's personal preference.
