I was exactly in your shoes, I now own a gh4, the main reason for that was the price point, but not only, I love how panasonic listens do costumers, how they keep upgrading the camera via firmware, etc, i'm not feeling that in other manufactures (at least not at this price point).
With that being sad lets not forget how crazy the sony is at low light, wich may come in handy, more for doc works or works that need an extremely fast turnaround otherwise its mandatory that your properly light what you're filming ;)

TL;DR: If you have the money to spend go with the A7s, if not, the gh4 it´s a great camera for you to have for some years, without having to upgrade the body for a long time. the only thing you lose its the low-light crazy performance but on the other hand you win internal 4k

One commonly used trick is to swob the food with a little oil or fat to get that punchy and glossy look, another one is to use as much as soft light as oposed to hard light. Dunno much more but rule of thumb is if it makes you hungry, it was correctly shot :)

You dint mention the camera that your are using.. but if it is any DSLR you might want to check 5dtoRGB since it gives you more color space so work with, specially since you are grading in Resolve ;)

thanks Jake! nice to ''hear'' those words :D

do you think its possible to be because of camera difference or the actually pacing?

Yup nicely thought.. Next time I'll definitely pay more attention to b roll
i actually shot some b roll stuff but with the gopro (i tought i'd use them in the BTS or something but honestly i didnt liked the way it looked..

And it is! thanks man!! really appreciated ;)
