I, too, found "Oppenheimer" to be a brilliant series and one of the finest offerings ever on American PBS. David Suchet was particularly effective as Edward Teller, as I recall, and the overall conception was spectacularly good. The only reason that the series doesn't rate a full 10/10 is for the low-budget production values in some areas. Actual content is absolutely first-rate in my recollection.
The Oppenheimer miniseries will be released in the UK on July 31st! It will be a Region 2/PAL set, but it would seem that a Region 1/NTSC set should be soon in the offing.
If you have a universal player in the US, you can order the series right now from Amazon UK.
