This image, though not in Blu-ray quality, shows the huge difference that exists between the first two Blu-ray releases
In 2013, Geneon Universal released the entire series on Blu-ray in Japan. The transfers are the same as the British Blu-ray, but the aspect ratio is the original 4:3. This set is significantly, perhaps even unreasonably, more pricy, retailing for upwards of £300 (or c. $400 USD).
The complete series was released on Blu-ray (as well as on DVD) on June 9th, 2015 through Shout! Factory and Timeless Media Group.
As of 2023, the series is only available in its original 4:3/1:33:1 format in the USA, Canada, Germany and Japan.
