Resolving power for different cameras

[Jonas Klittmark]

Has anyone seen a proper test comparing the resolving power of a 6K Dragon to an upscaling Alexa (and other cameras for that matter)? If not, why? Shouldn't this be one of the most obvious ways in which the Dragon is objectively better?

And please don't say it's self-evident. There are plenty of cameras out there that resolve nowhere near the resolution they output. And with advanced uprezzing it's not clear what kind of textures benefit from true sensor resolving power vs which ones can be blown up with acceptable results.

I'm a Dragon owner myself so I'm obviously hoping the results would be flattering for RED but either way I'd love to find out what the truth of the matter is.

I am sure tests like those already exist. If not, they will come soon.

A good starting point is to compare a 2k DCP on a 4k projector and the same test (obviously made with a 5.5+K resolution file) in 4k DCP projected on the same 4k projector. Put it in loop. If you've experienced this test, you can see what the differences are about. Now your test is between two manufacturers. I don't know the results as I never needed to shoot the other one.
