Remaster question - some help please

I have been off the grid for a while and I just need some conformation regarding the remastering of Rory's back catalogue. I want to purchase them, but want to make sure that I buy the actual remasters.
From looking at Amazon UK, it seems that Rory Gallagher, Deuce, Live In Europe, Blueprint and Tattoo are not actually remasters. However the albums from Irish Tour 74 are.
Please can someone confirm if these first 5 releases have been remastered and Amazon have got it wrong or have they not been released in the new format.
Sorry to be dumb etc, but I'd really appreciate some help before shelling out
