The Xbox One has 9.375% CPU clock advantage over the regular Playstation 4.
The eSRAM can also function as an L4 cache to bolster CPU performance, increasing that performance divide.
The Xbox One's DDR3 memory also has a slight latency advantage over GDDR5 which also benefits CPU performance. (I can do the math on this if you want me to?)
In a best-case scenario you could be looking at upwards of 15% more CPU performance for the Xbox One.
If you paid attention to various Digital Foundry videos you can see the Xbox One will sometimes have higher minimum framerates than the Playstation 4 in a fair few multiplatform games, especially when there are allot of entities on-screen. This is most likely thanks to the CPU.
On allot of these games that have Dynamic resolutions... When your framerate takes a hit, then your resolution drops, in the Xbox One's case, at a high resolution it's most certainly GPU bound, whilst at a low resolution it's CPU bound, thus it's not far-fetched to assume that in CPU-bound scenario's (And if there is no GPU-limits) the Xbox One should in theory be capable of a higher resolution than the Playstation 4 in those instances. - If all things are equal of course.
With that said, you are mostly right, this is unlikely to happen due to developers targeting for the hardware specifically and knowing what they are working with, but on the PC, if you pair up a weak CPU and a strong GPU, the CPU can and will hold your framerates back, especially minimum framerates.

Interesting read about console CPU's. Yeah I know about CPU bottlenecks on PC. By the way what would you recommend if I have head-room on PC, DSR 1440p with MSAA x2 or DSR 1527p no AA, because they mostly perform the same in many games, which one looks better?

DSR is basically Dynamic Down Sampling where you run the game at a higher resolution and downscale it, it's how you get bullshots essentially.
It's also similar to how Super Sample Anti-Aliasing works.
MSAA is lighter than Super Sampling as MSAA detects the edges of polygons and only increases the number of Samples there.
As for your question and as someone who has been gaming at 1440P for years... I will always choose 1440P.
It simply scales better, 2715:1527 is not an accurate 16:9 ratio.
Jaggies can also become more pronounced depending on the brightness and colour gradients and the contrasts used in the game... For example, if you have a very bight sky and there are some dark cliffs contrasting that sky, then you will notice the jaggies easier than normal.
DSR + 1440P + 2x MSAA should give a better result than DSR + 1527P, especially if you are scaling upwards to 4k.
