PRINTING Tier? (Patreon)

Greetings people!  I was thinking bout adding a 5$ tier that would have extra big TIFF files suitable for profesional printing in big formats and in CMYK.
I am thinking bout 4 extra files per month, older renders that will be carefully upscaled and filtered from 1920 x 1080 to 11520 x 6480 pixels.
Also they will be resampled from 24 bit to 48 bit and again 24 bit for better dithering.
Now there is a technical explanation - why CMYK format? what's the difference from RGB?
