I've noticed ( vascular load - and - antioxidant index ) options on Samsung health but when I go to use them it says ( you need a galaxy watch 8 or newer to use this feature) the watch 8 isnt even out yet, how is this possible? Do they mean one UI 8??
They either mean one ui 8 or it's a sorta placeholder till the feature is ready.
As brooklin said, the samsung news site does mention the watch 7 and ultra will get them too. I think the watch 7 might miss 1 feature but the ultra will get them all. According to samsung anyway
