She could be, last time she headlined EP was a medium capacity festival at 35,000, EP now is 75,000 apparently so she could very easily be a sub for this one. Someone in another forum said that she wasn't going to cart the backdrop all the way to Ireland between dates in Spain and Portugal. More often than not though, established touring artists sometimes have duplicate backdrops that can be set up in other countries for a tour. I believe Aphex Twin done this with the Field Day set in 2017, he had a much smaller backdrop setup in Dublin the following day for Forbidden Fruit. Speaking of which, he is another rumour for the blurred out name and is also touring between these dates in Bristol and Portugal.
