Do you think iPad tablets or iPhones will ever come with 4k screens sooner or later ?

4k is mainly marketing, especially for small devices like tablets and laptops...
My Surface Book 2 15in has a 4k display, but the ppi is basically the same as any iPad with retina display, other than the mini. The mini would still have a higher ppi than a 12.9 pro in 4k. Can I tell the difference? No. Anything above 190 ppi I can’t see the pixels... 1080p 13.3in I can see the pixels, but reduce that under 12in and I cannot see them anymore...

Agree. I have a 4K 13" laptop and would not pay a premium again for 4K at that size range. The display on my 2018 12.9 Pro is every bit as good.

Since the iPad is 4:3 it would not be true 4K but the resolution would be high enough that no one would be able to tell the difference.

That's not really how iPad resolutions work. Using the 12.9" as an example, it has a point resolution of 1366x1024 - that is to say if the display wasn't retina, it would have a physical resolution of 1366x1024 pixels. As it is an @2x retina display, it has a physical resolution of 2732x2048, so each point is displayed across 4 pixels, giving more sharpness to the image without changing its size. So the next logical step would be @3x, this is something we have seen on some iPhones, but not yet on an iPad. With that each point is displayed across 9 pixels (3x3 grid) so would require a physical resolution of 4098x3072. You could call that '4K' but it's not really what you're talking about. I do think this has a decent chance of happening, eventually, though that's a lot of pixels to push for a device that needs to maintain decent battery life, so perhaps a way off yet still.

The mini LED could assist with this or even the potential OLED.?
