No, it's not. It's a $1300 high end tablet, which (among other things) will not run arbitrary programs of the user's choosing, and which has aggressive memory management and background process restrictions. All of these factors contribute to 8 GiB being a reasonable amount of memory for such a device.

As far as I know even the newest iPad Pro is limited to 5GB per app, so if you use it for things like drawing in Procreate the 16GB upgrade does literally nothing.

Procreate's own layer limit calculator makes a distinction between the 8 GB and 16 GB chips.

Thanks, last time I checked that supposedly wasn't the case. Though an increase of layers between ~10-25% seems a bit underwhelming for the RAM upgrade.

You can definitely request more than that with the right entitlements.
