No worries, don't be too hard on yourself...
If they are in fact Aquila strings, then this poses and interesting point regarding hearing perception - as I've never heard anyone on UU, nor on YouTube describe ANY Aquila strings as 'warm', but in fact quite the opposite.
My own hands-on experience with
all of their ukulele strings bears this out as well. Across more than a dozen ukes, mostly different woods, they tend to sound either bright or somewhat brash when compared to most fluorocarbon, and nearly ALL nylon strings that I've tried, with nylon having the 'warmest' tone with the least sustain, regardless of tuning or tension.
Another difference in the sound and play/feel will occur depending upon whether your plucking/strumming hand attacks the strings with fleshy finger pads, or with your fingernails....hmmm
Could it be the wood combination that renders this tone?
or
maybe Brian (the OP) has nothing else to compare it to under his own fingers and ears in person?
This all reminds me that, like with many things, hearing perception is VERY subjective (and that can be a good thing, but makes absolute comparison difficult).
