Take note of this:

To give processes access to their entire 4 gigabyte or 18 exabyte address space, OS X uses the hard disk to hold data that is not currently in use. As memory gets full, sections of memory that are not being used are written to disk to make room for data that is needed now. The portion of the disk that stores the unused data is known as the backing store because it provides the backup storage for main memory.

Although OS X supports a backing store, iOS does not. In iPhone applications, read-only data that is already on the disk (such as code pages) is simply removed from memory and reloaded from disk as needed. Writable data is never removed from memory by the operating system. Instead, if the amount of free memory drops below a certain threshold, the system asks the running applications to free up memory voluntarily to make room for new data. Applications that fail to free up enough memory are terminated.

As for 1TB getting 6GB RAM instead of 4GB for 64-512GB, I think that's likely true. We already saw some Geekbench 4 results for iPad Pro models showing 4GB and 6GB RAM. Thus far, the ones that have JnnnAP motherboard have only 4GB and the ones with JnnnxAP have 6GB.
