Short answer - yes
Long answer - Yes. I'm not an expert on this matter or well experienced with gear but providing the headphone with more / ample power showcases more of the headphone's capabilities. Example, more bass or pronounced bass, airiness, detail and clarity
FOMO - Been there, kinda done that
Opposite of FOMO - Yes. I've gotten to a point where it ideal to demo an item(s) you're interested in, and only buying it if I like how it sounds OR if I have enough expendable income to blind purchase an item with the chance that I don't like it and never use it again or in the long term. I no longer buy (or try to) headphones because someone (e.g. reviewers) says "This is a great headphone! It's the best $$$ headphone at it's price point!" Or "This sounds better or is better than a, b and c headphone. GET THIS!"
I watch reviewers and their takes to get an idea of what I may like or maybe try something that sounds interesting and/or different than what I'm accustomed to
TL;DR If you like what you have acquired, enjoy it. Don't worry too much about other people's opinions. There are many great products out there. Some objective better than others, some people might have personal preferences. Important thing - enjoy what you buy
