Amati also did that on their entry level clarinets (Corton, Lafleur, B&H 400 etc.) back in the '70s through to the '90s which had a flute-style pad cup for the LH2 and RH ring keys - it was the same style pad cup you'd see on the trill keys and LH1 key on most flutes which had a dished centre with a groove running around it.

B&H 1010 and Peter Eaton clarinets also have domed pad cups with Y arms for LH1 (open G vent) and LH2 (E/B vent) instead of the usual pointed cup arm to the key rod or barrel.

Sometimes this is done to gain extra room, especially on the LH1 pad cup which is tucked under the throat A touch as that keeps the height down to prevent the underside of the throat A touch clattering against it.

Selmer use oboe-style domed pad cups for the LH1 pad cup (for the open G vent), but Buffet still use the traditional pad cup and arm and there's not a lot of room between it and the underside of the throat A touchpiece. Provided a thin pad was used in the LH1 pad cup, there's no danger of the throat A key clattering against it.

Other times this is done for comfort if the pad cups are in close proximity to the ring keys or it's done purely as a cosmetic thing.

I recently serviced a set of Schwenk & Seggelke 3000 clarinets (see attachment) where the E/B vent pad cup connected to the LH3 ring key (as part of the LH forked Eb/Bb mechanism) also had a domed pad cup instead of the usual style pad cups. The pad cup and arm are cast as a single piece instead of a separate pad cup soldered to a Y arm, then soldered to the key rod. That way there's fewer solder joints in close proximity to each other.

And then there were the DDR-era G.R.Uebel clarinets and others where the pad cups and arms were formed from a single piece of sheet metal with the pad cup milled out on the underside, so they all had a smooth flat top to them and that gave them a very utilitarian look.
