There is a bigger difference between 1080p and 4k then 1080p and 900p first off. Second off 40% difference is different in this situation in terms of GPU. Imagine an ant that is 1 mm long and there is another ant that is 1.4 mm long. You can't tell the difference unless you get a magnifying glass and even then it isn't a big deal. Now if the ant is 1 yard long and the other is 1.4 yards long then you can tell the difference for sure. This is obviously a bit of an exageration, but shows as numbers get bigger than the difference between the two is not only bigger but more noticeable.

yeah, but the difference will NOT be 1080p vs 4K. Simplifying 40% more power means 18% more pixels for each X and Y dimension. Indeed 900p*1.18 = 1062p, close to 1080p. Lets' say a game on PS4 Pro will have a 1440p frame bufffer with 6TFLOPS it could be just a 1700p frame buffer. Then sure, the Scorpio should improve other pieces of HW, but currently we know nothing about it. Still, the PS4 Pro has 3 times the power of any Xbone, so no, they are not and can not be compared.
Then, since we are talking about pixels, we are talking about something much smaller than an ant, so your arguments goes against what you pretended to say. Indeed higher the resolutions get and much harder it becomes to notice a difference. Just think SD vs 720p and compare it with 720p vs 1080p. The jump from SD seems much higher. Or even better get a 2x2 grid and compare it with a 3x3 grid. Night and day.
