Maybe Seafoam.

Definitely has a wichurana background.

Those leaves o do have that Seafoam iridescence.

I suspect it's a Poulsen rose. I don't think I have ever seen Seafoam bloom so abundantly. Iceland may have rose growing methods we need to know about! 😁

Moses.

Mine gets covered in blooms But they are not always as full as those shown. Sometimes they are. There are some spectacular images on HMF. I wish I could get a good pictures of the thorns as that's an indicator in my book!

There could be any number of possibilities, I initially thought of Asperin, among other white floribunda and ground cover roses, but a better guess would be Midsummersnow by Vissers. Those large clusters are typical for that rose. Not that I know it personally, I just considered it when I was looking for white roses once..

To me it looks like Bouquet Parfait.
