(I would insert the video here, but Blogger doesn't find it) Notice the black cow, which horns (although being still too upright) already show a basically correct shape with inwards-facing tips.
The grayish cow next to the aurochs-coloured cow appearing at 0:12 can also be seen on various photos on google, and her horns are more aurochs-like than in most of her ancestral "captive" Heck cattle from the 1980s. Still too upright, but going the right direction.
Be aware of the fact that only the horns of the two individuals I just presented here resemble the aurochs, their body shape and skull shape is still much too domestic and their size is certainly far away from their wild type as well.
The two individuals down below have perfectly curved horns, they'd just need to face more forwards and be larger and they would resemble the aurochs to the largest possible extent. Also their colour is aurochs-like, except the white patch on the forehead. Both cows are very similar (but they are not the same individual), perhaps they are related.
In 15 years, if everything stays as it is, we can expect cows with such horns to be much more common than they are now, because this horn shape is simply advantageous (when pulling and pushing their opponent in intraspecific fights), and there probably will be individuals with even more aurochs-like horns. In the current population, there are also individuals with the right colour, also some with the right proportions and body shape, but they never have all 3 wild type features at the same time. Maybe natural selection will produce such more aurochs-like individuals in the future. I propose selective culling to speed up that process.
