It remains the case that the law was brought down because of arguments about incompatibility with the current EU rules. Had those EU rules not applied, there would have been no basis for the issues raised in the judicial review. The legal technicalities of the judicial review process don't change that fundamental situation, nor does the lack (so far) of a CJEU reference.
Also yes, lots of other Member States have private copying exceptions, but most of them caved to industry pressure and introduced some sort of levy on their citizens in return. Those levies have been widely criticised, both for increasing prices of media and devices even where they would not subsequently be used for private copying purposes and for the manner in which the proceeds of those levies were distributed. If you read the EU resolution you linked yourself, you'll find it's extremely careful about the wording around that exception and it most certainly does not imply that the UK's private copying exception would be reinstated on the original basis or that similar levies should not be applied in the UK.
