Resolution and dynamic range are good. Bit-depth is better.
This reminds me of the DSLR resolution arms race except Canon is now obsessed with high ISO and resolution at the the expense of the color depth. Arri has it right. 14 bit images are far more important than resolution or sensitivity.
Sadly, they are the only way to display true black levels.
