I have this UK Blu-ray. At the time it was released (also 2011), it was the first Blu-ray in the world, but I think the reason for the term "Digitally Restored" comes down to marketing, along with the fact that at the time, most of these Blu-rays were also simultaneously re-released on DVD using the then-new HD masters. Since these DVDs had to be differentiated from previous ones, my guess is that StudioCanal thought that having "Digitally Restored" on the packaging made it easy to do so. My guess is yes. Barely, at the time. It's only because I had pre-ordered the 2019 UK release myself, and so I was already keenly aware that the "Collector's Edition" offered very little to justify the extra expense.
