I was looking for the 2014 movie on 4K Blu-ray, but it doesn't yet exist on the format. You know what does? And came out just this month? The 1998 Godzilla (which is a Sony movie, not Warner Bros.).
What is WB's deal? Echoing Jim01, why would they not being doing a big streaming/4K push of the 2014 movie leading up to the release of this one? This thread is proof that people are looking to revisit it in order to prep for the new one.
That said, I ended up watching it again on Blu-ray last night for the first time in a few years and it's good, no doubt, but man, I forgot how much Godzilla isn't actually in it. I thought for sure he had at least two big scenes before the finale. Nope. Just one, in Hawaii, and it cuts away before the fight even begins. Still, there's a lot to love, but it's such a flat movie at times. This new one looks about a hundred times more fun, colorful, and lively.
Just bought my ticket for the Chinese Theater IMAX next Saturday and I can't wait.
