Do me a favor: read my post 35. And consider that it sums up 286 pages of screenshots, in 32 experimental files dedicated to tone caps in my crowded archives. It took years here to collect that...
I read. Don't want to get in a rabbit hole, and this topic is a notorious one, years ago, when I had the opportunity, I spent days and days, I'd say months, using industrial level spectrum analyzers (not mine, I'll tell you in a ear, it was an off work personal research where I worked) testing different cap materials looking for answers, it was the time when I was so involved in hi fi stuff I tried almost everything.
I don't doubt leaking in cap has an effect, and I agree there is an effect on harmonic context certified by instrumental readings, but in my experience, when we talk about components in the standard conditions (not faulty, fresh, etc) it was well beyond audio range and, anyway, so subtle that I personally don't believe it can have an audible level even pulling the jacket to Laplace and Fourier.
My ears don't go beyond 12 KHz anymore, but even in my youth when I had a certified 20 KHz range, I simply didn't ear effect that was not ascribable to aforementioned components tolerance or problem with the specific item.
but, if you talk about electros, yes, no doubt, time and even voltage modify them, the effect is audible even in audio range, but no electros used in guitars (and in hifi signal paths too indeed, they are avoided like venom) . if we talk about radio range, of course, material do matter but we're on MHz
