Q: iPad 2 vs iPad pro photos capacity

In Settings > Photos & Camera there is an 'Optimize iPad storage' setting. Is that selected? Is that selected?

Any suggestion why I got 11GB more?

Is it possible that the iPad pro got a better screen resolution so it use more pixels that the iPad 2?

iTunes optimizes photos when you sync them to the device. If I'm not mistaken, the iPad 2 doesn't have retina display.  Since iPad 2 resolution is much lower than the Pro, your photos are downsized a whole lot more than the Pro. The difference may be a lot if you have the larger iPad Pro. Just my wild guess.

The iPad 2 has better resolution, I should see the photos from the tablet by the performance it has.

Air 2 resolution isn't better than the Pro either. I have no idea what comprarbarato is trying to say.

An iPad 2 (NOT an Air 2) and the first gen iPad Mini have the worst resolution of all iPad models that came after it.

The iPad 2 and iPad Mini DO NOT HAVE retina resolution touch screens.

So, photos are larger in file size ( possibly, native, full image resolutions) on retina screen model iPads.
