Daltile Perpetuo has a warm and a cool white marble look. It has multiple sizes and finishes also. It's also moderately priced, and Made in the US, so much more readily available than the import stuff that F&D uses.

I'm telling myself that you are shopping for tile to match your dog ❤️

TileBar.com has three that might be close to what you’re looking for. They have hundreds of large format tiles in porcelain so be careful - easy to get lost on that website.
Here is a photo of three I found right away.

When looking at these tiles you need to have a true white as the control color. These tiles can appear to have a "white" background until you put them up against a true white and then you notice that the tile is actually very gray, and some are very blue-gray.

If you can, go bigger on the size. Less grout is always a positive. I used 30" x 30" on my master shower walls.

I used Atlas Concorde - Marvel Edge - Royal Calacatta, but I just looked at their website and they no longer have that collection, which I bought 2.5 years ago. I compared a lot of marble-look porcelain tile brands/collections to find one that had a warmer white background and not a cool gray one.
