Is there still a "drop and fluff" process after an implant exchange where the pocket isn't adjusted?

Getting an implant exchange from 245cc Motiva Ergo Demi to 295cc Motiva Ergo Full. Both implants are the same diameter so my understanding is that no pocket adjustments will be needed. My implants are subfascial, and my original surgery was 2 years ago. Given that the pocket is already formed, will the new implants be settled into place right away or should I still expect a "drop and fluff" process? Also, will I be able to assess softness fairly quickly? My Demi's are so squishy but it took months for them to feel this way. Will the new implants follow that timeline or no since my tissue is already expanded?
