An excellent point, kind of. I think many folks miss the point of looking at their embouchure, at least in part, because they expect not to find a "picture perfect" embouchure which they imagine they should be playing with. The photos from the Farkas book prove that you don't need a picture perfect embouchure to sound good. But what defines a picture perfect embouchure? I would argue that every one of these gentlemen has a picture perfect embouchure. The facts bear this out. All played at an extremely high level, all were able to play pretty much anything that was put in front of them, and all sustained extremely long careers, a testament to the efficiency of their embouchure technique.
There are more variables to embouchure than I can list here, and that's just what I understand at this point. For me, a lot of the process of evaluating embouchure technique has boiled down to spotting problems rather than defining what is "perfect". I look at a student's embouchure and see if I can find any flaws in their production technique. These are usually accompanied by the sounds in their playing that match the problem. Past that, I start looking at sustainability in their technique. Is there undo stress in any aspect of the technique such that their embouchure is likely to break down over time?
As an example, let's take Peach's brief recording. Understanding that it is a very short example so many aspects are not able to be evaluated because they simply aren't presented, plus there are lots of missing elements that I would use to evaluate what is there (live quality sound, body position, horn position, head movement, etc.), I would say that your embouchure technique is fine. I don't see anything out of place until the very end of the recording. I suspect you went up to that very high note at the end maybe as a little bit of a joke but it did reveal how much you stretch your embouchure out when going higher and higher in the range. To what I understand, that technique will always produce bad sound and will become harder to manage as you age. Playing in the upper range requires vibrating embouchure just as much as any other range of the tuba. Pulling some of your embouchure out of the mouthpiece when going into a specific range can only hurt you, in my opinion.
Again, please understand that this is only a very limited analysis based on limited data and offered only as an example of how to go about evaluating your embouchure technique. No doubt there are many things that Peach has worked on with his teacher(s) that play into the entirety of his technique. All those factors come into play which is why the process of honest evaluation is so difficult to effectively accomplish. Normally I would give embouchure advice only after at least a couple of full lessons and even then, being very cautious to take all factors into account.
