Why do some whole grain products not show how much they contain per serving

[Green Warlock]

I like nishiki brown rice allot!It's the medium grain size variety.I thought all brown rice is whole.Nowhere on the bag does it show whole grain per serving with the yellow symbol.But my forbidden rice has it.Why is it not on some whole grain products?Not a deep concern,but I grown curious as to why

I have found that rice generally is confusing. I love wild rice soaked but it's not rice and I love black rice sprouted but it's not black lol. As long as you can sprout it then it's whole. Unless it's wild rice which doesn't sprout happily.
