Since tripping the Knox security actually alters (ergo breaks) the hardware my guess is it would void any warranty. The phone would be "damaged", as in useless as a BYOD phone and the security features would not work anymore. I would imagine in UK law it would be legal to deny warranty on a rooted phone with Knox compromised. The "Pre Knox" denial of warranty is very dubious legally in the UK. Samsung have got around that now.
We still pay our money and take a choice wether to root or not, only now with the new bootloaders and Knox I think anybody rooting can kiss their warranty good bye.
