When you shoot 5.7k you have 5744h x 3024v = 17,369,856 bayer pixels
8,684,928 Green pixels 4,342,464 Blue pixels and 4,342,464.
4k DCI is 4096 x 2160 = 8,847,360 RGB pixels = 26,542,080 total pixels(8,847,360 Green pixels, 8,847,360 Red pixels and 8,847,360 Blue pixels).
Test have proven that with 5.7k bayer pixel you can get a perfect de-bayer to 4k RGB pixels(4kR, 4kG and 4kB), whit a normal/fast de-bayer algorithm.
Some claim that they only need a factor of 1.25 instead of 1.4 to get a PERFECT de-bayer, till this day I have never seen scientific proof of this claim (theory + test).
Slashcam.de have just tested the BMPCC6k and it gives a PERFECT de-bayer to 4k DCI (as does the 6k Sony Venice).
The RED 5k(5,120 horizontal) and the UMP G2 4.6k(4608 horizontal) give a ALMOST perfect debayer in Resolve.
