I give you the display. However, if you compare with the 329 iPad and the older 9.7 inch iPad Pro... It shows that old iPad Pro is way overpriced.
The 9.7 iPad Pro is no longer in production and when they launched it two years ago, it was a significant upgrade across the board from the iPad Air 2 (which was the non-Pro model available at the same time) which was the same $599 for a 64GB model (compared to the 32GB in the Pro) but had a worse screen, a less-powerful and capable CPU/GPU/MCP, lacked a Smart Connector (so no Smart Keyboard) and didn't support the Apple Pencil. I'd argue the Air 2 was the overpriced model in comparison.
