There is a very good blu-ray set, now out of print but not crazy expensive, that has five different cuts: US theatrical, international theatrical, workprint, directors and final cut (which is the actual director's cut). That's the best version of the theatrical release that you'll probably ever be able to get.
Only the final cut is available on UHD or an in-print blu-ray (and I would guess streaming as well).
