Yes, you could say that.

Minecraft has a limited atlas size, all my textures were at the starting available on 4k, now this was okay as I did not have many textures on it, but now it has many new blocks and as a result, the atlas size was crossed which to be short means the textures wouldn't load and even to run 4k texture you need a minimum of 16GB of ram. Thus, I had to make all of it 2048x so I could keep adding more textures and there's not a very big visual difference, there's a difference but it's not much. Currently, you can find the 2048x textures on my Patreon exclusively only and 128x is available publicly. 2048x is the highest you can download, also they're many models in the resource pack too.
