Welcome to Sat-Universe Forum ,
WWE Feeds are always DVB-S2 - 4:2:0
only DVB-S2 - 4:2:2- 8PSK for UK Tour Feeds and that will not be happening anytime soon due to the pandemic .
Vu+ duo 4k will be just fine as will Zgemma h7s both are Linux boxes so you would need to understand Linux and how to Manually FTP keys i'm guessing you already know this as you said you have Vu+ duo 4k ,
zgemma h7s available from forum sponsor Here =>

both boxes are indeed 100% compatible and capable of opening WWE Feeds until they move to BISS 2 2610 then its really Game over
