iPad Pro M1 iPad Pro XDR display versus OLED

Higher brightness (or nits) does not mean better. Higher dynamic range does not mean better (especially if you can't display blacks and gradients correctly). If you have 10,000 nit master and show it on a 1000 nit display, do you know what happens? You should look it up before you decide one technology is better than the other.

Typically in this scenario TV does dynamic tone mapping apply to the image so that 10,000 nit master can display on lower nits tv. Tone mapping preserve the detail lost by blown out image. Dolby Vision does this dynamically on the content.

Yes, I know that, but by asking him to look it up, he may learn that the what is mapped will be suboptimal depending on the display technology. OLED will have a far better mapping than any LCD can produce because of the blacks. But a 10,000 master really is a complete waste as you are asking for the mapping to try to compensate for unnecessary ranges, and lowers the dynamic range, as opposed to being mastered with 1000 nit that high end consumer devices can contend with. Think of it like an 8 bit display trying to compensate for 10 bit content.

It seems the most important point is being ignored here. Sure, OLED has perfect blacks which lends to a higher dynamic range. That PQ is great to see, and very easy to see.... on LARGE screens! I doubt many would ever notice the difference on tablet screens of any size. Even then, you'd need a high quality 4K source, which can only be found on 4k Blu Ray. When you view compressed streams, that additional PQ virtually disappears.

The main advantage of OLED with tablets is improved battery life, and perhaps they can make the tablet a bit thinner.

That is just incorrect. Not only your perception of screen size , but also your source content. A source does not need to be 4k, nor does it have to be from a Blu Ray. I'm not sure why you think this. You obviously haven't looked at any small oled panels.
