It’s not uncommon for Blender devs to adjust value behavior of nodes from time to time. I’m pretty sure since this video the devs changed the color calibration between HSV and RGB. That may not be what’s happening in this situation but just to illustrate that it such changes do happen. @spikeyxxx always knows more about these kinds of code adjustments than I.
Practically speaking, my experience would say it’s important to learn that specific values in Blender are the least useful things to learn. Due to the ever-evolving code, specific values are a moving target and too variable to rely on from version to version. Rather the important thing to learn is WHY values affect a certain behavior. Learning this makes you resilient to working with 3D / Blender so instead of being stumped by “this value of X doesn’t work and I don’t know what to do” your response becomes “this value of X doesn’t work but I know this is the right value to adjust to get the desired effect so I will adjust till it looks right.”
It looks like you’ve already fostered this mentality! Keep up the good work and thanks for sharing the tip for those who haven’t learned that mentality yet.
