Node Noise Previews all Small and look the Same

[bigben]

Hi - in node editor all my noises pretty much look the same. All super small static, even if one is a super large, high contrast wavy turbulence for example. Know what I mean? In online videos I see other user node editors where all the nodes have previews that look distinct and so you can look at all the noises and kinda identify which is the, chips one for example. I can't in mine - all look so similar. I'll attach an example where the noises are identical and I've screengrabbed my node and how it looks in node editor and then the same one from a youtube video I'm following where the node's representation of the noise is distinguished.
