Experian finally updated and I've learned to make sure my CC is paid before each closing date as a recurring charge was keeping from AZEO1 and I didn't realize it. Path to 800 continues.
Crossed below 40% aggregate utilization (now 38.5%) and got 11 pt bump. Couple more months to get below 29%. 
Glad to see your scores rise. Also glad that utilization has short/no memory from month to month.

3 card accounts. Next month will be 1 of 3 with balance.
How is it possible to experience a 5 1/2% drop in aggregate utilization without other changes, such as, e.g., changes in individual account utilization?

Based on observation, unless you are >89% for individual card, for my acct I have seen ZERO FICO8 change on individual cards util. In fact, even in the various CRA on reports and category definitions they only reference aggregate and not individual. I've been watching my score and factors in detail. Ind card at 89% I got 5 points. 69% ind card util threshold got zero points and was only threshold crossed at that time. From what I see as I am paying my last card off, aggregate is the major factor and ind util doesn't matter. I'll keep track and advise if otherwise once my card gets to 49%.
The only thresholds of which I am sure are in individual utilization -- 29% and 49%.
In aggregate utilization I have never detected a threshold. However I believe I have detected that as aggregate revolving utilization goes down, my scores go up. But it's been gradual in either direction. No sudden bumps or thresholds.
In OP's case the change wasn't necessarily just crossing the 40% line, it was a substantial 5 1/2% drop from 44% to 38.5%. Gaining 11 points in FICO 8 for a 5 1/2% drop in utilization sounds about right to me.
