How big a window is on a certain resolution depends on the DPI scaling. Screen real estate would be roughly the same, but everything would be much more crisp with higher DPI. So with 2x 4K 28inch screen the screen real estate would be about the same to my current setup but everything would be sharp. Whereas with a single 4K 40inch screen i would get double the vertical space than my current setup and roughly the same DPI on a single monitor. It like 4 of my current Dells melted together into one giant monitor.
