I discovered this brouchure for Yamaha's Clarinets (in Japanese, for Japanese market) while replying the other thread about John Yeh:
https://jp.yamaha.com/files/download/brochure/2/865112/BCA1603.pdf
In page 3 (screenshot also attached), it describes the two families for Yamaha's (soprano) clarinets, SE and CS. Being an engineer while owning a Yamaha clarinet, I couldn't help but to share this. I know it is very technical.....
According to Google translate (and my own understanding, feel free to jump in if you can read Japanese or have more insights),
SE:
Soft and rich tone.
Concept is a warm, soft yet powerful sound.
The bore tapers are large.
Because few straight parts, it is a feature rich in width and tone. (not sure this is translated properly)
Tone holes are larger than CS series.
Bore taper is also spreading.
CS:
Clear and focused tone.
Outstanding performance, clear and bright tonal concept.
The inner bore and tapers are smaller.
Because the straight part is long, there is a straight core, realizing a projecting sound.
The inner diameter of the joint part connected to the bell is somewhat narrower than the SE series.
The resistance compared to SE will be slightly larger.
I am assuming the Ideal-G (available in Japan) is very similar to CSG in US, especially given the short barrels they both have. I suspect the SEVR and CSVR in US also share some specs with these SE and CS family clarinets.
(Being an engineer and IMO) Despite of the model names in the same or different markets, I think they must share some cores (such as bores designs, hence this SE and CS families) to save the manufacturing costs in tooling and labor. Majority of the sound and playing characteristics are probably built into these cores. The only differences between these models are probably wood, keywork (including plating), some of the designs that need to be hand finished (undercutting and padding?), and other cosmetic features.
Whether or not those differences (other than the cores) are significant enough to justify the premiums are up to the consumers. I suspect other clarinet manufacturers do this (sharing core designs among different models) as well. I know this is like saying Lexus ES is just a glorified Toyota Camry but to some people the additional features of the ES are worth paying for.
