A lot of variables here. Assuming the frame sync acts the same as it does on the other switchers, then a non-genlocked source will be 1 frame delayed or ~41ms at 24fps. Your multiviewer will have an additional 1 frame of delay so that will show video ~82ms delayed. I don't believe the ATEM 4K has a DVE, so you won't have to deal with the digital effects delay, but that would add an additional 1 frame delay for a high total of ~123ms.
Where you're really going to run in to issues is your projector. Assuming your source it 4K and your projector is only 1080p, then you'll need to use the scaler in the projector itself. That will likely take quite a few frames if it isn't a high end projector. Some can be 6+ frames or ~250ms... That combined with the delay of the ATEM will be noticeable.
I may be missing something, but I'm not sure why a large sensor would add more or less delay. You still have the same number of lines that need to be scanned at 1/24th of a second. I guess if there is a buffer between the sensor and the SDI output that could add delay. But that wouldn't have that much to do with the size of the sensor itself. I could be mistaken though.
Thanks,
