Same experience here. I had an apartment-size home fridge the PO had installed. I replaced it with the same marine version that originally came with the boat (even the screw holes lined up.) I found it used a lot less electricity. I went from being able to go less than 12 hours on my house bank (before hitting 50%) to at least 24 hours.

Some might say it wasn't worth it. It cost a lot more than an apartment fridge. I still run the genset once or twice a day if I'm at anchor or on a mooring, so I technically didn't need the extra efficiency.

On the plus side: It looks great. When I want to, I can skip running the genset. If the genset fails, I'll be OK for much longer; just motoring a few hours will recharge everything. If I install solar I might never need the genset at all. Less stress worrying about where my next hundred Amp-Hours are coming from is a good thing.

Overall, I'm glad I went this route.
