I do think there would be a temperature difference. I could be wrong. Easy enough to measure if someone has a unit.
I've had three compressor machines: Simac (which made good ice cream but was a pain to clean), KitchenAid (which was frightfully expensive, very hard to clean, and could not make satisfactory ice cream), and my present Cuisinart ICE-100 (which is easy to clean and makes good ice cream). The ICE-100 on sale for $234 was a good value. The ICE-100 is not all stainless steel and it probably does not have as powerful a compressor as some of the more expensive Lello models. But I don't think any of the Lellos have removable bowls.
