Since that issue seems to be licence-related (fast bandwidth costs a lot of money in licence fees as I have understood so far, I also assume more complicated controller layout and such),
It's bottlenecked by the way we communicate with the screen - over SPI. And the SAMD21 SPI interface can only go so high

Ok, so I mixed that up, thanks for the correction.
I am not good at reading datasheets ( especially the 2000+ pages stuff: http://ww1.microchip.com/downloads/en/DeviceDoc/SAM-D5xE5x-Family-Datasheet-01507B.pdf ), but if I get that correctly, the ATSAMD51 has more pony power than the ATSAMD21 on that part. Keywords like Quad SPI and 32 bit extension for SPI sound promising for me ;)
Well, I assume the ATSAMD51 had been in discussion while the development phase for the META was ongoing and I think you had good arguments against it ;)
[Edit] but at least dreaming about more RAM is nice :P
