If it ain't broke? 32C vs 30C/D--should I buy a new bra?

I first used ABTF during covid, and learned I'm a 32C. Finally, for the first time in my life, I bought bras that really do fit! Since then, I've put on about 10lbs, had a lumpectomy, and, well, also not bought a new bra, lol. I figured I'd remeasure, since there was some questioning on another sub if, given I'm only 4'11", a 32 band size was really appropriate for me. I put in my measurements and was given an exact fit of 30C/D, with a more comfortable fit of 32C or even 32D.

I really don't think a 32D would be appropriate. My (now elderly) 32C bras still fit me nicely in the cups. However, when I see examples of other 32Cs, I feel I am visibly less busty than they are. When I look at examples of what 30C or 30D busts look like, they look much more like my chest. But I'm scared to switch bra sizes given that I know 32C is comfortable, and I'm concerned about the sensory experience of a 30 band size.

Does anyone else in these sizes have any thoughts or advice?
