Edit: I had half typed following reply some time ago, I am not implying anyone does this, just sharing my thoughts on what few can do.
OP has good fish and enjoying the fish is more important. I had red dragons which didn't have most desirable traits but were beloved.
Original reply:
Naturally no food can do more than genetics.
The things that actually make difference and which I don't support at all are carophyll pink and hormones. Carophyll pink us just synthetic version of Astaxanthin. Naturally produced Astaxanthin is not as concentrated or cheap as synthetic. If you feed a lot it makes a difference. Hormones, this bit is very tricky, I heard from a US based breeder that Thailand based breeders use estrogen, I purchased a paper on hormonal control of nuchal hump in midas, in their experimenting they failed to induce hump through many hormones except HCG which they and I believe caused a feedback loop causing fish to produce more hormones. Now if other forms of mild estrogen that's used medically can do same then it's cheap to add those.
There are certain things I am not sure of but would like to talk about. Fish are seasonal breeders, environmental changes dictate the season to them and fish in favorable breeding conditions show better attractive traits, like for few fish it's hump and colors, I believe that's why high temperature causes better colors and hump, and may be high protein has similar effect. I believe other breeding favorable conditions would do the same.
