Yes and No. Presently, the UK is going through Brexit which has somewhat devalued the £ but you're correct in assuming that licensing agreements with the Major record companies in Europe are probably much more favorable than in the US but two things come to mind: the first batch of D~V MOR QUAD SACDs had to sell reasonably well for them to release the next batch and secondly, at least D~V is making an 'attempt' to branch out and release pop titles [Tower of Power/Main Ingredient] which may open the floodgate for future Pop/Rock titles [Jefferson Airplane/Starship/Philadelphia International,Harry Nilsson, etc].
And by my count, D~V has accomplished in two short years what AF's QUAD program acheived in three or four......by releasing roughly 31 QUAD SACDs (I'm counting each two~fer as 2 separate discs).
And the price D~V is charging IS miraculous.
But one thing, at least for the present, seems certain: in both the US and Europe, Warner and Universal QUAD/5.1 titles are OFF THE TABLE for surround reissue.
