I'm afraid I don't like Royal Canin, and I don't feed kibble but I do read up on it and try to make myself aware of the ingredients. These are the ingredients for the Labrador junior:
rice, dehydrated poultry meat, maize, vegetable protein isolate*, maize gluten, animal fats, hydrolysed animal proteins, minerals, beet pulp, fish oil, vegetable fibres, soya oil, fructo-oligo-saccharides, psyllium husks and seeds, hydrolysed yeast (source of manno-oligo-saccharides), hydrolysed crustaceans (source of glucosamine), borage oil, marigold extract (source of lutein), hydrolysed cartilage (source of chondroitin). ADDITIVES (per kg): Nutritional additives: Vitamin A: 24300 IU, Vitamin D3: 800 IU, E1 (Iron): 40 mg, E2 (Iodine): 2.8 mg, E4 (Copper): 2 mg, E5 (Manganese): 52 mg, E6 (Zinc): 198 mg, E8 (Selenium): 0.1 mg - Technological additives: Pentasodium triphosphate: 3 g - Preservatives - Antioxidants. ANALYTICAL CONSTITUENTS: Protein: 33% - Fat content: 14% - Crude ash: 7.3% - Crude fibres: 1.7% - Per kg: Calcium: 9.9 g - Phosphorus: 8.3 g - Manno-oligo-saccharides: 0.5 g. *L.I.P.: protein selected for its very high assimilation.
The first ingredient is going to be the largest proportion, and that is rice, unfortunately they don't tell you %'s, which is a bit of a niggle to me, if they aren't willing to put what percentages there are, is that because they are bad? I'm not sure why they're putting maize gluten in there, as dogs don't digest cereals very well, and gluten is something that dogs can be intolerant of, the same as humans. Any guess as to what the animal fats and hydrolysed animal proteins are? Beet pulp is a filler which a lot of foods have in, a lot of the additives they list are found naturally in many foods, so I'm not sure if they're added or added by default.
The OH weans his pups onto RC and is thinking of possibly changing, they do ok on it, but they are never firm and he's had a few problems over the years with it. The cost is also prohibitive, the first website I clicked on lists £16.49 per 5.5kg, and the rrp is over £50! I don't know what the price would be on a breeders scheme as I've never joined.

I can only comment personally on the one litter where I weaned pups onto the adult variety of Simpson's Premium Lamb and Potato, ingredients are:
Dried Lamb*, Deboned Lamb*, Potato, Beet Pulp, Lamb Fat*,Brewers Yeast, Lamb Gravy, Dried Egg, Salmon Oil, Minerals, Linseeds, Vitamins, Yucca Extract, Cranberries, Nucleotides, Mannanoligosaccharides (MOS), Fructooligosaccharides (FOS), Glucosamine, MSM, Chondroitin.
It does give the percentages on the bag, it's a niggle that it isn't on the website again (so maybe RC aren't bad but it'd be nice if they all had them on) but I haven't got one any more, the lamb content is 46%. The pups did brilliant on it, and I got a breeders discount for all the puppy owners, the puppy version is more expensive, but I simply don't believe in life stage foods, and the adult version is easy enough for Labrador pups to cope with. It costs £30.20 for a 15kg bag on the breeders scheme.
