Your setup "is" an etale $p$-divisible group over the residue field $k$ (uniquely lifting over $O_K$), so its $W(\overline{k})[1/p]$-admissibility is the slope-0 case of the Dieudonne-Manin classification, illuminating the comment in Sam Derbyshire's answer concerning the need use an algebraic closure of the residue field. | |
