Blur? What blur? So fsr the only thing to ho off on right jow are comosrisons made with Tomb Raider. And we srent rvrn surr yet how exactky tomb rsider is achieving 4k on thr PS4pro and if they sre using the tech. But one thing is certian, its going to be significantly sharper than 1440p so basically somehere in between that and native 4k.
And when you are that high on the IQ scale, such differences in resolution becomes a lot harder to spot. Either way it's a great tech cause it means GPUs would be able to accomplish a lot more with less.
There is also another thing to consider with this tech but I'll talk more on that in my reply below.

There are quite a number of docs out there explaining the tech and how it works. But it's basically something like this.
1080p = ~2M pixels
PS4pro Checkerboard = 1080p*2. = ~4M pixels (base)
1440p = ~ 3.6M pixels
4k = ~8M pixels
So what the PS4pro does is that it renders two 1080p images natively, 4k is the equivalent of 4 1080p images. So the PS4pto renders half the total resolution of 4k. Then instead of using software to reconstruct the other half, it had dedicated hardware that takes samples from the natively rendered pair and uses those samples to reconstruct a pair of fake 1080p images so to speak.
Everything gets compiled into a 4k frame buffer. You end up with an image that is sharper than 1440p, that has been upscaled to 4k but without the artifacts that plague upscaling.
