Is this a Genuine XHP CREE LED ?

It simply doesn’t look like a genuine XHP70 (any gen). Just compare with photos of XHP70s (in this case, XHP70.2 since only gen2 has phosphor all over the package) : LED test / review - Cree XLamp XHP70.2 P2 40E (4000 K) - The second generation of extreme overcurrent and light flux capability?
