There isn't any science to measure that stuff. Like the presentation of a closed IEM versus an open-air headphone, it just isn't applied or doesn't exist.
Your vents = spacious theory and 4-6kHz resonance angled driver theory is subject to scientific data too. For example closed CIEM's can sound very spacious, so another "A guess at best".
The FR spikes were a cause for concern in the Sony EX700, but given the green light in the EX600/800/1000. I think the EX700 has issues around ~1kHz versus the EX600, even though both look dead flat there, so FR has not correlated to my listening impressions, nor user comments, in my experience.
Spaciousness is easily determined with a removal and re-emerging of a vent, insertion depth is also a big factor, this is stuff that can be easily tested. Turing a driver at a 90 degree angle and placing it back the regular way just hasn't been done.. Headphones don't need to be involved.
Every angled driver IEM does exhibit that spike, that's the data (7550, 1000, 6000, EX80, EX310, EX90, 700LP, etc.)....
(the custom example) Yes, that's also a guess at best, you have to tell it how it is. Unless there's was a previous study suggesting it may the case or if it was proven to be outcome of the mechanism, guess at best.
There was never no green light given, the spikes have been improved in the new Sony line-up but still a concern. Maybe the problem isn't in 1kHz, wouldn't be surprised if something was misinterpreted there, 1k regions are more holistic, the latter spikes may be throwing it off for you.
