The difference is protein is really negligible. White rice has 3g of protein per serving, and this rice has 5g protein per serving. It may be “53% more”, but it’s 53% more of a very small amount to start with. The absolute amount of protein is still very low - lower than most other grains, actually.
I would just go brown rice at that point. This rice has no fiber which brown rice has. As far as the protein content, 5g is really not a lot, you would need to eat 130g of carbs to get 20g of protein. Brown rice also has a lower GI than white rice. But unless you are really strict on your carbs or have some form of diabetes, there is no real reason to stress about GI anyway.
